Maybe its because I try to do it from Russia, and Alexa app not available officially here, but I download it from Amazon app, so it works. I can speak with Alexa, but she/it don't recognize some commands like start or stop, and I cant control music with my voice. I add Deezer to Alexa app, add Deezer to Sonos app, but it does not work with voice control, only with buttons in the Sonos app. And I cant add different apps for music from Alexa app, only Deezer and Amazon Prime (which don't work in Russia).
I add iTunes, Spotify, Deezer, Google Music to Sonos app, but its cant control with voice.
