Thermostat keeps going "offline" without trying a different connection. I have to go to thermostat and physically change the selection which takes the convenience out of the expected access remotely. Also, says to check to see if all updates are completed, but does not say how. The only way I see is to delete app and reinstall. Not very user friendly. Our first Nest was purchased years ago. I did not expect the new and improved Nest thermostat would be inferior and harder to use.
