Problems with music app

Hello lillyann98,

Thanks for reaching out to the Apple Support Communities! We understand you are experiencing some issues with the Music app on your iPhone. We are happy to help provide some guidance.

It sounds like you've done some great troubleshooting steps so far to try to resolve this issue. To continue, we'd recommend checking to make sure that the Apple Music subscription you are using is still active so you can access the Apple Music service. Take a look at how to check your active subscriptions here:

We also would recommend checking your Family Sharing permissions to make sure that that sharing is still set up correctly. You can see the steps to take if you don't see shared content in this helpful article:
