Does that preclude taking pictures in advance? In other words, does the app immediately place said pictures up on a Tesla provided page or do you submit them there? I ask because I just had my trade in washed and waxed and, as would be expected it rained, so I'd hate to have to wash the car again in a week. I expect that would be the next step in my transitioning. OK, so that's a question, where in the process do they ask for pics?
You can take pictures in advance. You need a front quarter shot, full side, rear quarter, full dash from between the front seats, and title.
I had to transfer from my phone to my computer, reduce the image size, transfer back to my phone, and then submit. The mobile webapp only accepts individual pics up to 4MB in size.
