Hi, I have serious troubles with my Sonos Android app since a few says ago. It cannot connect to Spotify anymore. I've tried everything (re-installing the app, re-authorize the Spotify account, re-install the speakers (2 SONOS Play:1 and one PLAYBAR) but still the player stops working and I get the error message "Cannot connect to Spotify". I know that the Wifi is working, that the spotify account is okay and I can use the app to change into TV-mode but that's it. Any ideas what could be going on?
