Apple Music Genius Playlist not Functioning on iTunes

Hello, Collector_Pro.

Thank you for using Apple Support Communities! I understand that you're having trouble using Genius Playlists on your Mac. I'm happy to provide a few steps to try.

First, double check to make sure that your subscription is active: View, change, or cancel your subscriptions - Apple Support

Try turning Genius off, restarting your Mac, then turning the feature back on: Use Genius Shuffle, Genius Playlists, or Genius Mixes in iTunes on Mac - Apple Support

Then, try to force quit iTunes on your Mac, to see if the behavior changes the next time you launch: How to force an app to quit on your Mac - Apple Support

Let us know if these steps help! Take care.

Thanks for letting the community know that those links were helpful, Collector_Pro.

Cheers!
