Why can’t I change my Apple ID back to my iCloud Email?
I originally created my Apple ID by creating an iCloud email, months ago I decided to switch it to my outlook email and now I wish to change it back to my iCloud email but it won’t let me I feel like I’ve tried everything, turning off iMessage and FaceTime on my device, signing out of all media services (app store, Apple Music, Podcasts, Game Center, etc) all before signing out of my Apple ID account on my device and then attempting to change Apple ID email on a browser. Nothing. Anybody got any idea what I’m doing wrong?
