Appreciate your response to this and you're right about everything you typed. My only question is then what's the purpose of having Passive unlocking if one of the requirements on the phone is to have the app running (foreground or background). Meaning, if I have to remember to open the app at some point prior to approaching the car, then I have to be actively engaging in the unlocking of the car.
Another thing I've noticed is many a times I do pro-actively open the app let's say 10 minutes or so prior to getting into the car such that I give it enough time to 'wake up' and all that stuff. However, when I approach the car, it doesn't recognize the app being open. Turns out the app was automatically closed and doesn't appear in my 'Open apps' screen. Usually it's okay but now with the heat and probably carrying stuff in your hands, you now have to re-open the app, hope and pray it quickly 'wakes up' and recognizes the car coz sometimes you have to again shut down / close the app and re-open it to make the loading screen go away and make you feel dumb by how quickly now it's available to be interacted with!
