Adding a Child to Family Share that Already has an Apple ID
How can I add my child that already has an Apple ID to Family Sharing without creating a new Apple ID? When inviting the Apple ID to Family Sharing in the traditional method, the only category for the account that is available after accepting is Adult/Parent. However, when you select "Create Account for a Child" and go through the process, you have to create a new Apple ID. That seems to be unnecessary if they already have account. Is there a solution for Apple IDs that already exist for children?
