I had the Sonos skill added and it was working for the most part. Playing my Pandora on the each player via Alex voice control. and I could see in the Sonos app the art of the current playing song. I updated the players and although Alexa says it is playing the music in the right location/device, I don't hear any music and the Sonos App on the iphone does not show that it is playing anything. The iOS sonos app is also up to date. I use an Echo Dot.
