Once the Sonos app for Mac updates, I lose my Music Library. I then have to go through some weird way to get it connected again. This is the best way to get it reconnected that I have found:

Once I get it connected and able to hear songs from my Apple Music library, it only plays the songs that I have previously added to a queue or playlist. If I look for another song in my Music Library to add to a playlist (or queue), it tells me there are “No selections available.” I’ve tried updating my music library (I do realize it takes a while), but it doesn’t seem to help. Any suggestions?
