I cannot connect to the Nest App. I'm prompted to sign in with my Google account, I select it, allow access, and I am then transferred to the Google home screen (www.google.com). Account never adds to Nest and I cannot remotely control my device.

Keep us posted on how it goes.
I am able to sign into the Nest App now guys!!! The issue for when is when the App launched the browser to sign into a Google Account, I had Microsoft Edge set as my default browser. I changed my default browser to Chrome, and my Google account successfully signed into the nest app. I am an Android user by the way.
