Stop sharing playlists with other family members

Hi, nrow, and thank you for using Apple Support Communities. We understand that you want to stop sharing playlists. We'll be glad to assist. To stop sharing a play list:

1) Open your Music app and navigate to the playlist you want to stop sharing.

2) Tap Edit in the upper right corner.

3) Toggle Public Playlist off.

4) Tap Done

Aside from that, playlists shouldn't automatically be shared. If everyone in the family is seeing them automatically, it may be possible that each member is signed in with the same Apple ID. If that is the case, each person would need to sign in with their own ID.

We hope this helps out.

Cheers!

Hi, nrow. Your Apple Music membership is linked with your Apple ID. You use this Apple ID in the iTunes and App Stores to purchase and download new content, and also to verify your Apple Music membership and grant you access to the content. You can sign out (and verify if each person is using the same Apple ID) of Apple Music by signing out under Settings > [Your Name]

Here's a link with more information to check out:

Use your own Apple ID for Family Sharing

Take care!
