On my Plex Server, I have two Smart Collections (a.k.a Playlists), each having approximately 1500 tracks. These are easily browsable in the the Sonos app, but no tracks can be played from these Collections. The same tracks can be played if you navigate to the correct Album and play them from a shorter list. I guess the Sonos players are failing on the length of the queue, since all the tracks in the Collection are added to the queue…?
Do the players have a limit to the number of tracks they can handle being added to the queue?
