When trying to add a new Google Nest Thermostat with Google Home App on iPhone, Google Home gets stuck after I select "No" for "Do you have a Nest Account" and click "I Agree" on the screen "Supplemental Nest terms" screen, I get an error message: "Request failed" "Your request could not be completed". I tried force-quitting the app and trying again but get stuck on this popup every time. I've also tried switching from Wi-fi to cellular but no luck there either. Please help, I'm unable to complete the install of the thermostat because of this bug.

Thanks BoulderPaul, I was on the phone with google support and they mentioned the same exact thing. I too was using a small business gmail instead of a "gmail.com" email. After switching to a "gmail.com" account I was able to get past this blocker.
