I can select the Google Nest Integration. I enter my Cloud Project ID and click Submit with no error. I am then prompted for my Device Access Project ID, which I enter and click submit. I am then presented with a screen from Google saying that it can't link to project. No other information and no error. Nothing in the home assistance core logs. I've double checked the settings and I know that Project ID is correct as it returns the project name that I set, "HA Nest Project".
Not really sure where to look for issues - any suggestions are appreciated.
Just upgraded to the latest update.
