Some notices can be tapped to view the full content.<br><br>Multiple schools<br>If your children attend different branches, you can switch between them and read each branch&#39;s notices separately.<br><br>Account<br>View your account details, sign out, and delete your account from within the app.<br><br>Report a problem<br>Report an issue directly in the app, optionally attaching a single screenshot to help us understand what happened.<br><br>Notes<br>The app offers no in-app purchase and no in-app card payment.
