Hi all. 
I have Plex setup and working to play music on my Sonos. But the only options are to sort by album or artist etc.
I have a few mp3’s in a specific folder and for the life of me cannot figure out how to play those specific mp3’s from that specific folder.
The Plex app itself does allow access to specific folders but it seems the Sonos app doesn’t.

Or am I missing something?
