after update 80.00.20 all devices not available

I have the same problem. 
Updated one iPhone with the new app. No speakers are found. 
another iPhone with the old app is working fine. 

Uninstalling the app and reinstalling it makes no difference. It says initially it found my system but then no speaker shows. 

Seems more like a network issue, rather than an app issue. Try wiring a single Sonos device to your router if you can. Or unplug all Sonos devices from power, then reboot your router. Give the router a couple of minutes to come back up all the way before plugging back in your Sonos. 

If neither of those suggestions help, I would recommend that you submit a system diagnostic if you can, and call Sonos Support to discuss the issue your system is experiencing.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Reporting same issue here. Was using previous version of the app. My iPhone asked me to update to the latest version. After updating the app, all my speakers disappeared. (Speakers are still visible on my wife’s phone on the previous app)

Exactly the same issue for me. Updated to the new Sonos App and now, no speakers can be found, but all are still working and accessible on my IPad using the old App. How can anyone say that this is a “network issue” when the only thing that has actually changed was updating the Sonos App on my iPhone??? Please explain. 

*FIXED SPEAKER ISSUES WITH 80.00.20*

I experienced the same issues as reported by others where all of my Sonos speakers were no longer accessible via the Sonos app. I was forced to update the firmware to 80.00.20 and I kept getting a message that i needed to update my speakers. But the update process failed when I was using my iPhone.

I ended up downloading the Sonos app to my MacBook and I was also prompted to update the products when i launched the app. The updates actually completed and then i was able to see my speakers again in the iPhone app and desktop.

Hope this works for others.

My issue (on 80.00.04) is that the Roam, if powered off, does not appear - but in previous app versions it did.  It meant I was reminded to go and turn the Roam on.

Thanks ssw1234, but the sonos app on my MacBook was already up-to-date and says there is no update available for my speakers. :( 

Same here, I tried to use my MacBook sonos app but it gave me same message “ no update required “ and all of my speakers and boost now showing up.

ill try to do the hardware one of my speakers and see if this will help! 

Absolute shambles.....can't access anything on Amazon Prime or MyRadio and can't add TuneIn. They better back out thus upgrade ASAP!
