Family Sharing for Apple Music is not working.
I have added a family member to my family sharing but am still unaware how they can use Apple Music, they open the app and it asks them to trial or create an account.
They have to accept the invitation and include Apple Music in the shared services (opt-in). They should be signed in on their device with the same Apple ID as was used for the invitation. After the invitees accept your invitation, each member of your family group will have access to Apple Music.
