Google assistant endless loop

I was excited to see integration with Google assistant, however when I try to add sonos, the following happens:
1) I go to voice services and add Google Assistant
2) this takes me to the Google screen where it authenticates me using the same email address that's on my sonos account
3) this then redirects me to the sonos authentication
4) after authenticating on sonos, it says I need to register my speakers to my account, so I click Go to Sonos App, and the process starts all over again.

This doesn't make sense. My speakers are registered to my account. When I go to the sonos website, and sign in with the same email address, I can see all of my speakers. Elsewhere in this process it says if I go to More > Settings > Account Settings and I don't see "Account" I need to update my sonos system. I do not see "Account" - I see my email address as the linked account and then I see Transfer account. Where is "Account"? I've also confirmed my app and speakers are all up to date.
