This is what I do as well and works perfectly.
My standard way of keeping the car on in these situations is simply to make sure when I shut my driver's door, it's not quite all the way shut. In other words, it goes past the first "click" so that it looks shut from a distance, but it's not actually completely shut. The car still considers the door "open" and will keep the A/C on, music playing, etc. I find this much easier than messing with the app on my phone (of course, I use the app - or camper mode in my S - in the situations that call for it - like when I leave my dog in the car while I go into a store or something similar).
