Wyze thermostat doesnt display anything below freezing

ambient temperature is well below freezing but thermostat doesnt display it.
is this normal operation?

I’m not sure the thermostat itself is rated for use below freezing.
Is it powered up?

Yes powered up. After i posted this question here, i received confirmation from an owner of three Wyze Thermostats. They all stop at 32°F like mine does. The actual temperature can be much much lower. They do however still function to raise heat.
