Unable to Successfully Connect Google Assistant to Nabu Casa Cloud

I’ve been trying to get a paid Nabu Casa subscription working for the first time.

I’m migrating from a Google Assistant manual setup to a paid Nabu Casa HA cloud setup.
I made sure to wipe/remove everything of the manual configuration out and started fresh the first time to make sure, but refuses to sync.

The service seems to go through with “Linking” and is confirmed in HA, but fails and resets as soon as I try to do anything.

I can approve the skill in the Google Home app by selecting “Allow Access”, but as soon as I try to do anything it fails and i have to setup the Google Home app again.

The app is ready to be configured:

It doesn’t seem to stick, its not listed in the approved apps.
For a second the cloud is setup and I can click the “sync entities” button:

Then I immediately get an error, and the linked status is broken:

It’s like its stuck in a loop.
