My biggest annoyance with the mobile key is that my wife & I are both set up with it, and if it sees both of us it seems to randomly choose which profile to load. I have to click on profiles, select mine, and wait the 20 seconds for my profile to swap back before I can get going. With her profile, I get her set of stations/apps, her carplay connected, etc.
I'd love to be able to say "unlock the car, but don't swap profiles unless..." a) you see her sitting in the driver's seat, b) I hit the screen to confirm a swap, etc.
Yes, I even have the "Prompt before loading configuration settings" so it doesn't move the seat etc - but it still automatically unloads my profile & logs her in.
