2022: Totally WORTHLESS! Not able to connect to or re-authorize Spotify connection. POS App@ 2021: Even Worse! The connection/system disappears on my PC, iPad and Android. Anybody want to buy 7 Sonos speakers? 2020: Hit or Miss Functionality. Constantly have to turn off WiFi, close the app, and turn both back on - sometimes even while music is playing over the speakers.
