Are you using Spotify from the Spotify app or from the Sonos app?

I do both and same problem. I’ve made all types of uninstalls and installs. Also tried with other phones 

I have the same issue and havend find a solution yet

Hours of chat support yesterday and got told to call support. Talked to support today and answer was that this is a known issue Sonos have with Spotify and at the moment no solution. I got told to wait and see if they can fix this issue. 
can’t recommend someone to buy Sonos at the moment
 

I hope that they solve the issue rather quick. The only reason i bought Sonos was to listen to Spotify

The guy I talked to didn’t sound very optimistic. 
I guess most of Sonos users play Spotify so if it’s not fixed people will choose other options
