SUCCESS!
So this evening I deleted my Google Project and Action and started from scratch. I rebuilt it all. I documented each step and still no go. You may have sensed my frustration in my last post, but, I had the same results. It kept asking me for oauth2 authorization.
Well due to unrelated reasons, I was trying to fall asleep and my mind was racing… I couldn’t sleep and I started thinking about this some more. I decided to to try wiping the Google Home app cache and IT WORKED! The crazy thing is that I’ve uninstalled the app many times, so why it took clearing the cache, I don’t know… But that was the last thing that got it working.
As I mentioned earlier, I also meticulously documented my steps on this rebuild. I’m hoping to have some time in the next day or two to get it cleaned up (easier to read, sensitive info sanitization) and shared for everyone.
