Linked accounts
My daughter has an iPhone which is linked to my account. We have just put her sim into a new iPhone and when we have gone through start up, it has set up as a replica of my phone- messages, phone contacts, apps etc. How do we rectify this? I know it will have something to do with Apple ID etc- however both phones were previously on same Apple ID as she is only a child. How do I get back to her phone settings on her phone so she is not receiving my messages etc and vice versa? Thank you.
