I have been having issues controlling my Sonos system via Google assistant.
I decided to unlink and readd Sonos to Google home.
When doing so, I am presented with two identical systems, with no way to disringuish one from the other.
I only have 4 speakers all under one system, so don't understand why two show.
Oddly, if I select one it only adds two devices. If I unlink and try with the other, it only adds the other two devices.
Anyone have ideas on what the hell is happening here?
Thanks

Exactly the same issue here. Sonos app shows just one system (with all my Sonos devices in it), but when linking Sonos to Google Home it is showing 2 systems with devices split between them.
I recently changed my router, so maybe that's related.
I've been told by Sonos support this is a known issue, and I should check every couple of weeks to see if the latest software release resolves the issue 
What network setup do you have now out of interest?
I have a single subnet, so everything is on the same network, but I have one Sonos device wired and the others are on WiFi. I put everything on WiFi, rebooted all sonos device and now I see just one system with all devices in it as expected.
Interesting, two of mine are wired and two are on WiFi. I think this means I am in a SonosNet configuration.
Can Sonos support comment on this issue and advise if perhaps this issue only affects SonosNet setups or when you have a mix of wired and wireless?
I will try moving mine to all wireless and see if it also resolves my issue
