Spotify doesn't stream to Chromecast anymore

[skoty]

Hi guys!

Maybe you can help me: my Samsung s4 mini worked very well together with severeal Chromecast Audio devices. But now it doesen't stream the music from Spotify anymore. The devices are all shown in the list, the sound, that the connection is established plays, but the Spotify-program still says "connecting...". Other programs like youtube still work without problems, so it should has to do something with Spotify.

What I've already tried: Delete the cache and the program, restart the mobile phone, reinstall Spotify -> still the same issue.

Any tips?

Best greetings, Thomas
