My appointment time was at noon, but I arrived at 11:15 and they took care of me right away with the paperwork and then we went to the car. The Tesla guy couldn't get my car to show on my app even though all the paperwork was signed. He had to go back inside and change my appointment time to 11:15 in their main computer to get it to work. So, it appears that your appointment time in the computer has something to do with this, too.
