Just updated to the new app and found that the main way I play music to my speakers has been broken. I utilize “Music Library” > “Folders” to play music so that I can choose which FLACs I play over the Sonos system (I had to downsample some HD FLACs so Sonos can play them). This has always worked with both the S1 and S2 controller apps.
However after the update, it will still play the song I selected but it shows “No Title” for the song title, does not show time played/remaining, and does not proceed to the next song as normal if you were to select a song in an list of songs from an album. Everything works fine if I go into “Music Library” > “Artists” or another method of selecting songs.
