Is one of you (saidmasoud vs. jandrese) using the Nest app and the other using Google Home maybe? I tried out a Nest thermostat briefly and found it confusing that there were two different apps with different featuresets.
I originally had the Nest app where we could both access it using our phones, but my wife clicked "yes" when the Nest asked her to "upgrade" to the Google interface and there's no way to switch it back.
