This is working for me if I pause the ‘airplaying’ music and wait 10 seconds and press play again, it starts re-playing straight away, but perhaps there’s a time-out period. How long are you waiting between pausing the music and starting it again?

Just tested it - it’s immediate, I can ‘pause’, then ‘play’ immediately, and it doesn’t play, or I can wait a while and ‘play’ and it doesn’t play (Control Centre shows that the iPhone is still AirPlaying to the speaker in all scenarios)

Sounds like the speaker is somehow intermittently losing connection to your sending device. - it’s definitely working okay here for me. I’ve tested it multiple times a few minutes ago.

My initial thoughts are to maybe try a reboot of your router, speaker and mobile/sending device and see if that fixes things, also check for any updates too for both your speaker and the mobile device. I’m using an iPad on iOS 17.1.1.

Thanks, fully up to date on all software (including this week’s iOS 17.1.2), reboots done, problem persists, no change 

FWIW, I’ve updated my iOS devices to 17.1.2 this past week too and everything is still working fine with AirPlay here. Not seeing any issues. It maybe best to reproduce the issue, submit a Sonos system diagnostic report from within the Sonos App, note it’s reference and then contact/chat with Sonos Support Staff via this LINK and see what the Staff can perhaps suggest to resolve the matter.
