Hi there, ChairmanKenny.
I see that Family Sharing has been setup to share an Apple Music Family Membership as well. But, when they try to set up Apple Music on their device, they're met with an individual membership invitation. I'm happy to help.

If you have issues with your Family Membership:
- Make sure that all members of the Family Membership are sharing their iTunes Store purchases.
- Make sure that you're signed into the iTunes Store with the Apple ID and password that you use to share content with Family Sharing.
- Sign out of the Music app, and then sign back in.
Learn what to do if you still don't see your family's shared content.
Take care!
