I have an iPhone 8 with iOS12.1. When it’s in my pocket it has unlocked the car successfully at least 95% of the time for months. Last week I got an Apple Watch 4 and since then the car is unlocking on approach only about half of the time. When I unlock my phone I hear a click and the car door is unlocked. I don’t even have to tap the Tesla app, unlocking the phone is all it takes to unlock the car. I haven’t changed any settings on my phone that I know of, just paired the watch with it. Does anyone have an explanation for this?
