...have been using Spotify through Sonos through the trial period. Trial Period ended and I upgraded. Trying to play Spotify through Sonos and it still says I need to upgrade to Premium. I have allowed Sonos to upgrade Spotify info and it gives me the notice that I can close the screen and go back to Spotify. I go back to Sonos, click on Spotify and it tells me to follow the link to upgrade to Premium again.
