I've installed and signed into the Tesla app on my iPhone. I've looked at "scheduling service" on a YouTube video and when they tap the "Schedule Service" listing on the apps main screen in the video, they get a list of various common problems that one could schedule service for. When I tap the "Schedule Service" listing on my iPhone, the app searches for appointments and all that appears is a delivery appointment I had that is in the past and that was mis-scheduled to begin with. If I tap "Modify or Cancel" my screen shows the appointment information, but no way to cancel or delete it. I just want to delete the mis-scheduled appointment and get the proper screen that will allow me to schedule service if I need it in the future. I tried deleting the app and reloading it onto my iPhone, but still get the same result. Am I missing something?
