There is an issue with the new sonos app (black emblem) on android device recognizing music selected to play, nothing happens. A fix to this was using the old (gold emblem) v2 application on desktop to select and play music.
After doing this, the app (black emblem) on android device then recognized songs selected to play and functionality is back to normal. Not sure if this is a home network issue or the mobile application being a bug fest which it is, no where as near smooth as the previous (gold emblem) v2.
