I just got my Mini a few weeks ago and have done about 30 flights. I've been trying to do the Quickshots, but it has only worked once, and not ever again. I can choose the Quickshot I want, I can successfully draw the green box around myself, and when I'm ready, it counts down THREE, TWO, ONE, but then nothing happens. The drone just hovers there looking at me blankly. Any tips on what's happening here?
