I feel your pain. Sorry to hear about your accident.
Had a similar experience.
I updated and rode it around to make sure all was okay at lower speeds with some maneuvering. Felt like all was good to go. When I was going about max speed I wanted to check to see if my max was over 13 mph yet. Opened the app and BAM!! Was wearing a helmet and wrist guards, but still messed up my elbow, knee and hip. Pinky finger holding the phone took a slight hit. Couldn't figured out what caused it, but starting to think when I opened the app my finger accidentally tapped the upgrade button (even after I upgraded). Ugh!!! There were a group of 5 people around me which were shocked about the accident, but still like the ideal of the board. Obviously, I told them they must still be working on their QA at this point (while trying to stand up and retrieve my board).
Board wouldn't start after that and I had to limp back to the office (board in hand). That's when I noticed the app bug (always prompting for an upgrade)
