Doodle saves its progress to our server every time the app returns to the Learning Zone, a child presses collect my stars or a child signs out. But it does need a data connection (3G, 4G, 5G or wifi) to do this. If it doesn't have a data connection, then it saves the progress on the device instead (see here for more information on Doodling offline).
Make sure to press Sign Out
When a student finishes a session, make sure that they tap this Sign out icon to guarantee the session has been saved.
Check connection to the server
In the app, navigate to Settings > Work Programme. From there, you can check whether the data has been synchronised with the server.
A green tick, as shown below, is good.
If you see a red "X", tap it, ensure you have a data connection, and then tap Retry.
For more information on Doodling without data connection, see here.
