Apple-ID - iCloud email address change
I have changed my Apple-ID. This change was not transferred to iCloud. As a result, iCloud is now continuously asking me for login data:
iCloud does no longer accept my password for my old Apple-ID.
When I use the “password forgotten” process it leads me to the Apple-ID login. Here, my old Apple ID is no longer valid:
Any ideas how to solve this?
