Hi, I can see this issue has been raised before, but I was wondering if anyone has found a solution? 

I have reactivated my Apple Music subscription and all my previous albums, songs and playlists are there and available in the Sonos App, but any new albums or playlists I add in Music never become visible in the Sonos App. I have tried removing the Apple Music service from Sonos and reinstalling it, but that makes no difference. 

Any suggestions?
