Email already in use with another Apple ID
I switched to apple for the first time when I got this phone 2 years ago. When I set up my account it said something like “my email was already in use or connected to another Apple ID” which is odd bc I use the email everyday and it is my first Apple product ever. Hmmm 🤔 can anyone help me gain insight about this or how to change it?
