How long is configuration download taking?

Gerzom

My Smart Thermostat is showing the symbol for configuration download now for several hours is this normal? Also my room temperature is set to 20 degrees is the app, yet the actual room temp is 19.4 and I can't change it on the thermostat as it is downloading..... I just installed the system 3 days ago. I tried to reset the thermostat, but the pictogram stays the same.
