Sunroof only works when car is "on-line"

I forgot to add a subscription! I also forgot to add four and a half minutes of unrelated rant before getting to the point! SKIP TO 4:25! It seems the intended start timestamp gets lost when uploading the link to SN!

With Mercedes it is even worse: A youtuber mechanic and Merc aficionado only realised that some of the features were subscriptions rather than bought when they "failed" shortly before he tried to sell the car. This really is becoming ridiculous!
