Our iPad was initially set up for my wife but has now been passed on to my son. As part of this we made an iCloud account for him and changed to the iPad to use it.
The problem is that the apps on the iPad were downloaded on my wife's account, which is no longer logged in and none of them will update. I do not know the password for this former account.
Is there any way to move the app to the new account? One app in particular cannot simply be uninstalled and reinstalled or he'll lose his progress.
