Unable to unlink girlfriends account from mine.
Hi. A couple of years ago I borrowed my girlfriends old phone for a few day and ever since, her account has been linked to mine and I can't figure out how to remove it. I tried to create an account on a website using my apple id and I scanned the QR code on my iphone to sign in with my apple account and it only gave me my girlfriends email as a choice. I was unable to choose my account to sign in.
Any ideas on what to do. She is part of my family sharing but her account shouldn't be showing up.
