Google Assistant - No Devices Found

It seem s so disappointing that Sonos can't figure this stuff out. To say it's released in Canada ( couple months after US release) and then for so many users having so many issues. I guess the long awaited 18 months was not long enough for them to figure this out with Google. I too like others suffer from it showing in GH but you go and ask it to play something and Google doesn't recognize it.
Troubleshooting notes or suggestions are terrible as none of it works. One suggestion is to look in the sonos App and room setting and look for Google Assistant- Well it does not show there. IT does not say if this is for all models of Sonos to see it or is it just for Sonos One /other newer models.
I am certainly glad I have not been investing more in to their hardware.
VERY DISAPPOINTING like the last several releases of new speaker quality. What happened, you were once my pride and joy of an audio system. It seems you went to focusing on paying high end people to be in your adds and not focusing on where the industry is today. The pass is the pass and your company can only suffer if your not paying attention or staying up to date to the world of devices today.
Just to clarify, you will only ever find a voice assistant in 'Room Settings' if the speaker has the voice services capability... so it will obviously only apply to the products that have that ... i.e. the Sonos One (gen1 or 2) & Beam. You should see a section called Voice Services and whichever assistant is installed on the device is shown in that area. You can also change some voice service settings too, by choosing either Google Assistant or Amazon Alexa. For example you can switch off the 'wake word' chime sound.

I can’t speak for Canada, but GA on Sonos for Music playback is working okay here in the U.K.

Thanks for the clarification you provided on when you see voice assistant under rooms. So does voice assistant work for older sonos speakers or must you have at lease one of the newer speakers. It certainly doesn't appear that way. I have PLay 5 first gen, Playbar and sub and Google home hubs. Is it just OK for playback in GH. Maybe I already gave this product more attention than I should and maybe I should just sell of my gear.

Yes, so if you had say a Sonos One with GA installed called ‘Kitchen' ...and an older Play: 3 called 'Bedroom' for example, then you can say to GA on the Sonos One...

”Hey Google, Play some music” ... this will play the music on itself in the Kitchen
or..,
”Hey Google, Play some music in the Bedroom” ... this will play the music on the Play: 3 (Bedroom) device.

Likewise, I have a Google Home Hub Mini and I can say 'Hey Google, Play some music in the Kitchen” and it will play on the Sonos One (Kitchen) as just mentioned in my previous post.

Yes thanks
But I don't have anything new. And what I have doesn't appear to be recognized by Google When I say OK Google play (Artist Name) on master bedroom - Google response Sorry I can't do that yet. Despite seeing it in GH

Going back to Alexa

I am up and running. It turns out my Cisco Enterprise network was not passing the required MDNS traffic during setup. In order to discover the devices, the Sonos Speaker needs to send MDNS packets (UDP port 5353) to the mobile device doing the setup.

I setup a very old WiFi bridge and connected my mobile device temporarily to that SSID and configured the assistant. They still work once that old SSID is gone.

I changed some settings on my wireless controller and got it to work.

Under the MDNS settings, I need to add the Google Assistant setup with this service string "_gasetup._udp.local." (without the quotes).
