Since this morning my Sonos System is unable to connect to Apple Music.
Here is what I done so far resolve the issue:
Re-connect the Apple Music account
Now connect successfully
Re-start Sonos App phone and router.
Other service than Apple Music are running without issues.
If I choose a song to play the msg appears „Not able to connect to Apple Music“
I checked the Sonos service page and no issues with Apple Music are displayed.
