Download app assiated with AppleID
We moved ISP's about 3 years ago.
My parents have run into an issue. We've updated the AppleID, so in the App store it shows current one, but when we try and download an app iPhone asks us to supply credentials for different AppleID.
I assume she forgot she downloaded this app before, but my conclusion is she must of when we were with another ISP...
We no longer have access to that email, account, so we couldn't reset password for that even if we wanted to
I know purched apps are different to the AppleID, not always the same one you signin with, But the problem, in this case, its a 'free' app.
Is there a way I can update so this free app will download on my "current" Apple ID??
I tried signing out and signing back in,,, didn't work it still asks for password for this other AppleID?
Since then, we've reset and restored iOS too.
There was something I read backup and restoring would work (eg either local, or through iCloud, and erasing all content and settings before restore) but I'm kinda skeptical...... That may be the last option, but would prefer others first.
