I installed my first nest thermostat yesterday. Spent several hours trying to get the thermostat to connect to the app. The thermostat worked fine - it is powered on, controls the AC, and is connected to both the wifi and my account. However, I consistently get an error on the final step. I followed all of Google's recommended steps. When I called support the guy just repeated those same instructions but had no other solutions. I cannot find any working solutions online - the only instructions that seem to work for others are specific for the learning thermostat. Here is a screenshot of the error screen.
