My four Sonos Ones decided to stop working right around when the latest updates came out. My app controller keeps telling me to update, but returns a 1101 error when I try to do so. I've rebooted the whole system several times, cannot update, and also cannot submit diagnostics.
I can however use the Line-in to play from my record table and group players together/see all of the speakers in the app, as well as airplay music from Spotify to the players, so they must be online and connected to my wifi.
Any help is much appreciated - this is super frustrating that I can't submit diagnostics or play any music.
