I have a P3A, and an iPad Mini 2 with the DJI GO app. After I takeoff, I try putting the switch to the "F" position, but nothing happens. The DJI video about the waypoint feature shows a dialog popping up on the screen regarding waypoints. Nothing happens on mine. I DO have that "multiple flight mode" switch set to on. I tried pressing all over the screen to see if there was something else I needed to do to "activate" that dialog after I put the switch to F, but I don't find anything. What am I doing wrong?
