Flew at night in an area where I'm familiar with. I used the Litchi app and for some reason I lost total connection. I did not panic because I had visual of my Aircraft the entire time, and after I seen that the aircraft was staying on its designated course, I was certain that this app is far better than the DJI GO app. If I had been using the waypoints section in the DJI GO app, my lack of confidence with said app would have kicked in and I would have panicked. Although I lost complete connection with my aircraft, Litchi maintained its course and continued to film said flight.
