The app works great as a phone key with its hybrid bluetooth/data functionality, but my only issue is walking up to the car and having it be unlocked. It only seems to work half of the time? I'm on the latest version of iOS with the latest app installed, bluetooth enabled, and "always use" toggled on for the location services functionality of the app. I know others have experienced similar issues, but I have yet to see if anyone has "solved" it. Any input/advice?
