This app is killing me. Work just fine for the AC, I can change the schedule no problem from the app. But the heat schedule will not change, it will not allow me to save it. Since I have radiant heat as a main heating source, i can't control the floor temp. Worked fine last season, not sure what was updated or needs to be updated with I the app but they need to get on it.

Longest user agreement and privacy (lack of) disclaimer I've ever 'had' to agree to.. now the thermostat won't connect, it said "waiting for connection" forever, so I cancelled, was going to try again, but then it said that I cancelled an update.. now it is connected, but won't update, won't give the option to connect the app.. Reset everything, still stuck on waiting for connection, this is after successfully connecting to WiFi, I see very minimal traffic in my router, nothing being blocked..
