Apple Music
My daughter has a family plan but we try to share and nothing is working. How do I get Apple Music on my daughter family plan?
iPhone 13 Pro, iOS 16
Seems up to six people can be sharing
You will need to receive an "invitation" from your daughter to join family sharing.
If she wants, your daughter could likely add another member to her family.
For details: She can scroll to:
"Invite people to join your family"
in Apple Support's article: Set up Family Sharing – Apple Support
All the best :-)
