I have 3 Sonos speakers (one beam, two Ones) with Google Assistant enabled in all of them. Each of them has a name (Living, Dining, Kitchen) and I have made sure that under the Google Assistant settings, ‘Default music speaker’ each one of them has been chosen, respectively. When I say “OK, Google, Broadcast <message>” I get the response “looks like there aren’t any other speakers connected on your home network so I can’t broadcast your message.” When I try the same from the Google Assistant app or the Google Home app on my iPhone, it just searches the web for that phrase. When I try the same from the Google app (so, not the Assistant, not the Home, just a third app, the Google app) it works! I have removed the voice service from all of them, delete the Google Home app and re-installed, re-set the home, but still the same. Any advice?
