Family share child's age is wrong
My child's birthday is wrong on their account. It shows that they are 18 but they are only 14. How do I change this under the family share account?
iPhone 12
Question marked as
The age comes from their own Apple ID, not the Family share.
Log into their account at https://appleid.apple.com with their Apple ID and password and update their age there.
