My FordPass app froze and would not open on my iPhone XI Pro for over an hour. I deleted the app and started again. I didn't think to reset the ParK so I was without the ability to start the car. I totally forgot the passcode. I have had quite a bit of problems in the past with the key not detected but there always seemed to be a way to get it to work in a relatively short amount of time. I do feel very insecure to rely on this feature right now.
