I contacted Sonos support unfortunately after 2 hours they were still unable to help me troubleshoot the issue. I have changed to a WiFi 7 network and since then I haven’t been able to play music via Airplay through my move and beam. I however can play music via the Sonos App through my move and beam.
Based upon what you posted the issue is not with Sonos. Also as a point of correction you should have said..,”I can’t play music TO my Move or Beam via AirPlay. AirPlay is an Apple feature. Therefore the conflict is with AirPlay and your network.
I suggest you contact Apple support.
