Does anyone have any information on how Shared iPad mode works with iCloud. I was under the impression that work and projects are synced to iCloud so that user can sign into a different iPad and carry on with their work. I'm finding the Photos (gallery) is automatically syncing to iCloud and follows the user around. But other apps like Explain Everything and Pic collage don't upload to iCloud. They seem to be local only so this data is cleared when they are removed from the iPad as a recent user.
Do I need to enable anything to force apps to automatically sync to iCloud? Or do the users needs to manually save their work to iCloud each time?
