I purchased the Sonos device as it said it had the capabilities to connect to Plex. I have set up my router to do a port forward. I have set up Plex to manually specify public this port and connect remote works. I am able to play music from other devices (several Roku devices) connected within the same network as my Plex server. When I try to get my Sonos to play through Alexa, it will not play the music. So, I tried to use my iPhone to play the music on my Sonos using the Sonos app. I can see the Plex server and I can see all my music, but when I try to play a song, I receive an error saying 'Unable to play 'song requested' - unable to connect to Plex. Has there been any resolution to this problem yet?
