Operations to Be Especially Careful About

Performing operations immediately before a service suspension may result in the operation not completing normally, or completing with a delay after the maintenance has ended.

Examples:

• Registration/export operations using CSV files
• Operations related to the manual archive feature
• User invitations / manual updates and publishing / task distribution, etc.

We apologize for the inconvenience, but please refrain from using Teachme Biz immediately before a service suspension.

Viewing Manuals During Maintenance

During maintenance, manuals will not be accessible via web browser or mobile app.
If you need to refer to a manual during the maintenance window, please prepare in advance using one of the following methods.
