Problem after updating Apple ID
I've just changed my Apple ID to my new email address. Phone (11pro) working ok, if I log in on an Apple website I get the auth code on phone.
Problem is in Settings, under my name it says "Update Apple ID Settings" where it says:
Apple ID Password
Enter the password for
"the email it shows here is old ID"
When I put password in I get Verification Failed An unknown error has occurred.
Any ideas?
