Same issue. Works on iMac but not Macbook M2 both running OS 15.0. On the MacBook M2 the web version works; however, not the desktop app.

Interesting. Have you called Sonos Support to let them know? Unfortunately, they don’t monitor these forums, and getting hard data to them quickly might be helpful. 

No, I haven’t. Guess I need to. 

I have similar issue

If you are having the issue on a MacBookAir M2, then I suggest deleting the Sonos desktop app. Then reinstall from the Sonos website. Try Version 16.4.2 / Sonos OS: S2 / Build: 81158074 … then open, sign in, connect to an Existing System. 

I I have installed the latest sonos desktop app, it is a iMac intel running macOS 15.01

Same issue here. Have to navigate to LocalNetwork and toggle Sonos on and off and then it works. No available sonos app update, latest macOS sequoia dev beta.

It does work without issue with my phone and iPad. Just a pain in the butt.

I have the same issue.  Have reinstalled S1 app, checked fFrewall and also Local Network,, nothing works.  Has anyone found a solution?

Glad you got it sorted out! It's wild how a simple toggle in settings can fix something that takes hours on the phone with support. Definitely filing this one away for future reference—thanks for sharing!

Thanks for commenting, but you appear to have misunderstood my post.  Reinstalling the S1 app and checking the Firewall and Local Network settings did NOT solve the problem, so I am asking if anyone has.  How about you, SONOS?
