We don’t have a bridge, unhooked the speaker that didn’t fit the recent upgrade, are using the new controller and still the four play 1 speakers we use constantly lose connection to music services. I mainly use Spotify but it’s happening across the board, the alarms set up to turn on radio stations all just bong the Sonos charm and it’s driving me nuts! I know friends who all seem to be having similar problems over the last months or so, is the system doomed?!
