I have a stereo pair of Sonos 1s in my kitchen. Tonight, they weren’t showing on the Sonos App and they failed to connect via Airplay. Alexa was working, so must have been internet connected. I’ve twice reset them and reconnect them ( Amber/White flashing, Green… discovered…. setup… rebooted ) and they’re not appearing. On Airplay, they are ‘unknown room’ but cannot connect
What else can I try ?
thanks
