Thank you for your continued patronage. Currently, when using Chrome (version 143 or higher) on Android tablets, an issue may occur where the OS is incorrectly identified as "Linux". ■ Affected Android Tablets: Google Chrome 143 or higher ＜Impact ①＞■Affected Feature: Post-Login Page Settings ■Issue Description: During the OS/browser compatibility check performed at login (a feature that verifies the device, OS, and browser version when a user attempts to log in, controlling whether login is permitted or denied based on predefined conditions), the affected devices may be incorrectly identified as "non-compatible devices." As a result, a "non-compatible device" warning screen appears before login. ■Impact Scope Based on Admin Settings The impact on users varies depending on the administrator's settings. This setting is located in the "Supported OS/Browser" tab of the "Post-Login Page Settings" screen under "System Settings" in the side menu. ・ Post-Login Page Settings The setting to allow or deny login is configured on the screen below. *The default setting is "Allow Login". ① When "Allow Login" is set: A screen indicating the device is not supported will appear before login, but users can still log in by clicking the "Login" button on the screen. ▼ Screen Image (At Login) ② When "Do Not Allow Login" is set: A screen indicating the device is not supported will appear before login, and users will be unable to proceed with login (the system will prevent login). ▼Screen Image (At Login) ■Request to Customers ② If "Do Not Allow Login" is set, cases where login cannot be performed using an Android tablet may occur. We apologize for the inconvenience and kindly ask that you consider changing the setting to "Allow Login" if necessary. 　 ＜Impact ②＞■Affected Function: OS Restriction for Course Access ■Issue Details: The OS restriction function for course access during content learning (which checks the device's OS when a user attempts to learn and controls whether to "allow access" or "deny access" based on pre-set conditions) may unintentionally classify the above-mentioned devices as "unsupported devices" during verification. ■Impact Scope Based on Administrator Settings If settings have been intentionally changed from their defaults, the following impacts may occur: Example) Cases where the affected devices may unintentionally be unable to access content OS Restriction Method When attempting to access content using an OS other than those specified above Do not allow access ■Request to Customers If you have changed settings such as "When attempting to access content using an OS other than those specified above" from their default values, we kindly ask that you consider changing these settings as necessary. We are currently investigating the cause and working on a fix, but resolving this issue is expected to take time. We will provide further updates as soon as there are new developments regarding progress or our response plan. We sincerely apologize for any inconvenience this may cause to our users.

Thank you for using learningBOX. Today, learningBOX has been updated to Ver. 4.0. We would like to introduce you to the various functions that have been added and improved with this update. Enhanced functions Content display based on diagnostic test results The "Linked Content" function has been expanded to automatically display the most appropriate courses, folders, and content for learners based on the results of diagnostic tests. This maximizes learning effectiveness by providing an environment optimized for individual learning by presenting the most appropriate content based on the learner's proficiency level and evaluation results. *For details, please refer to "Linked Content Settings. View Illustrative Materials (PDF) Expanded content operation in Course Management (beta) The UI for Course Management (beta) will be expanded to allow for more efficient content management. The content management screen used from Course Management (Beta) has been revamped, with enhanced pagination and refinement functions to make it comfortable to use even when there are more than 10,000 contents. In addition, new functions have been added for converting folders to courses and for moving folders/contents to other courses. *For details, please refer to "Course Management (beta). View Illustrative Materials (PDF) Improved usability and notification of notification functions Administrators can check the status of read and unread notices for each user on the list screen. In particular, by narrowing down the list to users who have not yet read, it will be possible to immediately identify users who have not checked their notifications. The unread status is also displayed in the Notices panel of the user's dashboard, making it easy to see at a glance the status of unread notifications. In addition, it is possible to identify users who have not yet read an announcement and resend an announcement notification e-mail to those users. This allows you to thoroughly disseminate important notices. The resending of e-mail notifications can also be sent as "important information," regardless of the individual settings of each user. *For details, please refer to "Notification Management". View Illustrative Materials (PDF) Batch download of correction data for scoring Grade administrators will be able to download corrections attached to grading data individually as well as in batches from "Grading Management". This new feature will greatly improve operational efficiency when handling a large number of student data. In addition, downloaded files will be organized and saved in a folder structure based on grade information. *For details, please refer to the "Submission List". View Illustrative Materials (PDF) Control the maximum number of accounts in a group account The specification for checking the maximum number of accounts that can be registered in a group has been changed. From now on, only users whose account status is "enabled" or "suspended" will be counted as the number of accounts in a group. Therefore, if an account is "deactivated," there will be an opening in the group's available number of registrations. This change allows for more accurate and flexible management of the maximum number of accounts. *For details, please refer to "Group Registration". View Illustrative Materials (PDF) Added "Latest and Highest Score Refinement" function to the Score by Content screen. We have added two new functions to the Grades by Content screen: "Display only the latest grades" and "Display only the highest grades. This makes it easy to find and tabulate the latest and highest scores when exporting CSV data, even when participants repeatedly study and respond to questionnaires, quizzes, tests, and so on. As a result, the time and effort previously required to manually organize data can be greatly reduced. In addition, this new refinement feature can be used to manage a variety of grades, including quiz tests, surveys, diagnostic tests, and more. *For more information, please see "By Content". View Illustrative Materials (PDF) Content Allocation by API Linkage Supports Login ID Specification The Content Allocation API now supports the specification of login IDs as a method of specifying users. This allows users to be specified by an array of login IDs when allocating and de-allocating courses, folders, and contents via the API, enabling more flexible user management when linking with external systems.

Thank you for using learningBOX. Today, learningBOX has been updated to Ver. 3.1. We would like to introduce the various functions that have been added and improved by the update. Enhanced functions Flexible content creation through API integration To enhance integration with external systems, support for SCORM 1.2 and PDF has been added to the Content Creation and Update API. This makes it possible to load courses, folders, SCORM materials, and PDFs into learningBOX via third-party applications. After content creation is requested, the progress of the process can be monitored asynchronously by using the "Content Creation Status Check API". This is an optional feature that requires a customization contract. *For details, please refer to "Third Party Applications". Redesigned and expanded functionality of Notice Management The design of the announcement management screen has been redesigned. The screen for creating and editing announcements has been improved, and rich text content can now be created. In addition, we have added a function to insert the URL to the detailed page of the announcement into the email template, making it easier to guide learners directly to the detailed page. *For details, please refer to "Announcement Management. Added evaluation by tag to CSV output of grade list The CSV output function of "Grade List" has been expanded. This allows the results of the "Grades by Tag" (tag name, score, distribution of scores, score percentage, and evaluation) set for each content to be included in the CSV file for output. This function is expected to be used to link performance data for tag-specific evaluation to external systems, such as existing school administration systems. *For details, please refer to "CSV Output (Grade List)". Allows groups with other functions to be specified as the publication destination for products, seminars, training programs, and curricula! The range of groups that can be designated as publication destinations on the Create/Edit screen for products, seminars, curriculum, and training has been expanded. With this modification, target groups created by other functions, such as the EC function, can now be selected as publish destinations. This enables smooth operation across functions, for example, allowing only users who have purchased a specific seminar product through the EC function to take subsequent training courses. Controlling Progress Posting at the Time of Fraud Judgment The behavior of anti-fraud functions (facial recognition and browser monitoring) for video content has been improved. Under the previous specification, when a student was judged to be cheating and was unable to take the course or was forced to exit, his or her grade would be "Learning Completed" and there was a possibility that he or she would have achieved the clear condition. In this modification, an option has been added to "Do not include" the results of a student who failed facial recognition or was forced out of the course due to browser monitoring in the study screen. This will allow for proper management of progress posting at the time of an incorrect judgment. This option only applies to video content. *For more information, please refer to "Fraud Prevention".
