Hi,
I ran a Sonos update yesterday - which updated my Sonos speakers and iPhone/iPad app. Since then, my two Sonos Amp (newest Gen) are not visible in the app. My Play:1s remain active and working.
The both amps have a solid white status light - as though they’re connected to something.
I’ve tried resetting both. They appear in the App until I try to play music - after which, music fails to play and the zone is no longer available though the app.
Anyone else seen similar? I’ve used Sonos for years and never seen such an issue. I don’t believe the unit(s) are faulty. That would be very unlucky for both to go at exactly the same time.
