Widespread Issues with Sonos and Airplay not working
It is clear from searching Airplay on this support page and Google that something has happened to multiple users to stop Airplay from working seamlessly with Sonos products. I play music to my Sonos Era 100s and 300 once or twice per month via airplay but tonight it is not working. I tried resetting all devices per other posts and factory resetting etc…. Best case scenario it will play a song for like three 3 minutes and then drop and not play further until I reset everything again. This used to be seamless. I dont have further time to troubleshoot this but somebody either at Apple or Sonos has dropped the ball here. If its Sonos please fix asap. If I cant get this stuff to work next time I need to play music I am just going to ditch all my Sonos products and switch to Bose which is shame because I thought the Sonos sounded better than Bose. But Sonos is useless if the Airplay wont work.
Reddit has some threads on this too - here is one
