Hi ​@hrdennis, welcome to the Sonos Community!

I’m sorry to hear that you’re having issues getting your Move 2 working. There was previously an issue where a sign-in loop would occur, but this was resolved and shouldn’t be affecting systems anymore. First, make sure that you’re using the correct account details; Your Sonos.com account and community account details are different, so if you’ve used a different email address for the community, you’ll want to use your Sonos.com address.

If the app is still asking you to sign out and sign back in as the owner, try resetting the app by heading to Account → App Preferences → Reset App. You’ll also want to make sure you haven’t disabled any app permissions, as this can prevent you from fully using the Sonos app. 

For the Move 2 not playing any audio, there could be a few reasons. Make sure Move 2 isn’t muted (it’ll have a solid green LED on top if it is) or on low volume, then try to use Spotify Connect and stream directly from the Spotify app as a test. If it works, then try another music service from the Sonos app, such as a free radio service. If both of these suggestions work, then you’ll want to reauthorize Spotify in the Sonos app by heading to Account → Content Services → Spotify → Primary Account → Reauthorize Account, then test playback from the app.

If you can’t get playback to start only when you use the Sonos app, make sure the app permissions aren’t disabled as suggested above, or try a different device with the Sonos app installed. If we can narrow down to what does and doesn’t work, it’ll help with further troubleshooting. 

You can always submit a diagnostics when the Move 2 is playing and reach out to our support team, as they have the necessary tools available to look into your system and help you resolve this.

I hope this information helps!
