Nest app is telling me to add my thermostat. It is already installed. Nest app used to work but now it doesn’t. It told me to get an entry key. So I went to the thermostat, followed the directions, went into settings, went into Nest app, saw the words “thermostat is connected” and that’s all I can do. There are no choices to go into the Nest app setting to get an entry key, no matter what I try. It’s a dead end. So, I am asking how do I get the entry key? I cannot sign in to the Nest app on my iPhone without it.
