I need help with changing my Apple ID from a third-party email provider to an iCloud email address
Good evening,
I need help with the following topic, changing my AppleID from a third-party email provider to an iCloud email address. I've jumped through some hoops already and I was able to successfully create a new iCloud email address and then unbind it from the appleid in hopes that I could then add it under my reachable at section on my appleid.apple.com account page. Unfortunately it's not working and I am unable to add it. Furthermore when I try to login to the iCloud email address that I created it now gives me a verification error stating it is not associated with an appleID.
Has anyone successfully changed a gmail email AppleID to an iCloud?
Thank you,
