I can't add Sonos to Google's Home or add Google Assistant to my Move.
Both approaches fail after giving my Sonos credentials, telling me to register speakers to my account. I have 10 speakers registered to this Sonos account!
I used to have it all working, specifically allowing me to use my Sonos Port as the default speaker for a bike mini, in my kitchen.
This all broke, so I removed the integrations and started again. But it added my V1 Connect, not my V2 system.
So I moved my V1 Connect to a new Sonos account, leaving all my V2 stuff on the original account.
Now I get this issue when trying to add Google Assistant integration to my V2 system account.
