No connection to Sonos (after Update 7.3) - Can't play this right now

[bambu_78]

After the newest Sonos-Update (7.3) I have no connection from the Spotify App (Premium Account). There is always the same message in Spotify "can't play this right now".

Is there a solution for this problem? I would like to use Spotify as main-player for my songs like before.

With Sonos I can play the Spotify songs (like from the playlist), but can't play local songs. Don't know if this is working before. Never use this.
