I know there have been a few posts on Google Nest WiFi Pro mesh setups but not seen any definitive answers. 
 

I have installed the mesh WiFi and whilst the Sonos speaker (S1) seems to have found and connected to the network (e.g. I can use Alexa and start internet radio) the Sonos app does not show any connected speakers.  
 

Has anyone managed to get Sonos working with Nest WiFi Pro? I do not have the option to connect via a wire or use the original router as it’s too far away - it needs to connect wirelessly to the Nest access point.
