Changing store Apple ID on a phone - is there an alternative to reinstalling every app?
iPhone apps (and perhaps other purchases) are tied to an Apple ID. Specifically the Apple ID specified as "Media & Purchases" Apple ID (MPAID) at the time of purchase.
If the phone "Media & Purchases" Apple ID changes new purchases will get the new MPAID. Old purchases, however, remain tied to the old MPAID.
If an app is updated the user is asked for a password. iOS does not specify the Apple ID, it just asks for a password. It wants the password associated with the MPAID used at time of purchase.
The only way I know to switch apps to the new MPAID is to delete the app and reinstall it.
Is there a better approach?
PS. Both the old MPAID and the new MAPID are part of the same family sharing group.
