How do I change my iPhone's signed in with same Apple ID to different ones?
I have my phone. I have a new iphone12 for my childm(18+). I tried setting it up, and appears to be mirroring everything that's on my iphone due to the cloud. What should I be doing to set it up properly? I just cant figure it out. Ive added emails and phone numbers to the account. I deleted them. I added them back. Help!
