Well, yes; the preheating itself works just fine. No problems there.
However, in the not so distant past (arount Christmas), the car also used to turn on defrost of rear and front windows in low outside temperatures. This was shown in the app by either the defrost symbol (and text) and in the latest APP version showing the rear and front windows in redish color.
This defrosting is now missing (not shown at least).
Yes on mine it shows both defrosting and battery heater on when warming the car, that was what I ment.
