My sonos system consists of the (Arc, Era 300 Surrounds, Sub gen 3). I’m writing this due to issues i have with the connectivity of the system, recently (I’ve got no clue if the issue is due to the recent Sonos App revamp) all of my speakers refuse to connect together with the arc leaving all of them standalone units that cannot be setup again, the setup menu appears in the app but after trying just loads indefinitely. I’ve tried resetting every unit including the Arc and it worked for a couple of days but then the issue repeats itself. I honestly have no clue as to what to do to get the system up and running again, this is really frustrating as i often use Dolby atmos and I can’t seem to get the full experience with a system that isn’t functioning. Not to mention that i also have a Sonos One pair which completely disappeared from the system and a Sonos One SL that disappeared from the system as well.
