My son's account was setup with the wrong birthday so it is showing as adult account. I changed the birthday to the correct birthday and removed and readded him to our family account but it is still showing as an adult account. How can I fix this?
See:
Update the birth date associated with your Apple ID - Apple Support
To change a birth date to any age below 13,* you must be a member of a Family Sharing group, and your family organizer must approve the change. After you change a birth date to any age below 13, you can't edit it.* Learn more about Family Sharing.
If that does not work, I would suggest to:
Contact Apple for support and service - Apple Support
Good luck!
