i am using an iphone 8+ on ios 12.1. everytime i open app when connected to aircraft, the app crashes. I can see the camera for about 2 sec and the app shuts down. I have deleted and reinstalled app many times, restarted my phone, cleared video cache, re-formatted sd card, and even changed the date to see if that helps. I have no video on the sd card or app. Not sure what to do from here.
