Every time I initially start playing music through the S2 app to 2 speakers (a Sonos One and a Sonos Roam), the app says it is playing to both speakers, but only the Sonos One is actually playing any music. I have to go into the ‘Now Playing’ section of the S2 app, uncheck the Roam, then re-check it again in order to get the music playing out of both speakers correctly.
This happens EVERY time I have stopped and then restart playing music.
