I think this can lead to "data loss", since suddenly the expected data is not being uploaded anylonger.
Instead I would

• warn on Android that folder does not exist -> user can recreate it or adjust auto upload folder OR
• recreate folder on server side, so that auto upload keeps working

(I tend to second)

Whatever the solution is gonna be, it should also handle deleted subfolders, either

• because it was deleted on the server
• or because not all subfolders have been successfully created on the server after setting up a custom auto-upload
