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 or wifi) to do this. If it doesn't have a data connection, then it saves the progress on the device instead.
Make sure;
When a student finishes a session, they tap this Sign out icon to guarantee the session has been saved.
Checking connection to the server;
If you select Settings > Work programme, you can see whether data from the app has synchronised to the server
A green tick is good.
If you see a red x, simply tap on it, make sure you have data connection, and click Retry.
For more information on Doodling without data connection, see here.
