iCloud storage on iPhone error "unable to load Storage info" and impossible to do iCloud backup
Hello! The problem started first when I upgraded iOS from 13.something to 14.2 on my iPhone 8
That iOS update made my iPhone 8 freeze and very unstable.
In several days I bought a new iPhone 12 Pro. I transferred data from iPhone 8 to a new one directly during the first setup.
Now iPhone 12 Pro works fine but it clearly has some problems with my Apple ID and iCloud:
- it has never backed up - I tried several times and it just keeps on hanging for hours...
- it consistently asks to update Apple ID Settings so "Some account services will not be available until you sign in again" - I did several times but it keeps throwing an error "Verification failed. An unknown error occurred".
- My Apple Music does not download...
I have a suspicion that during that update from iOS 13 to iOS 14.2 on my old iPhone some "old cache" remained and now I have this castrated access to iCloud and Apple ID services.
Please help.
iPhone 12 Pro, iOS 14
