Old email address won't let me log in to FaceTime and iMessage
When I try to log in to FaceTime and Messages on my iPad Air (4th gen) running OS 16.2, it first asks me for my current Apple ID, then it asks me for a password associated with an old email account I'm no longer using. I can't delete that old address from the log-in box. I have no trouble using FaceTime and iMessage on my iPhone 13, but I can't use it on my iPad because I can't log in. How do I delete that old email address from my Apple account?
