I've been trying out course lock, home lock, poi, waypoints, etc. I loaded Litchi yesterday. Today, Litchi wasn't updating gps map, so I went back to DJI GO. When I switch to F, I no longer get the usual menu. It also tells me "Course lock or Home lock is enabled". Sure enough, the craft behaves like Course lock is on. I can't exit out of Course Lock. I think I've looked through all the menus. I've disconnected, reconnected, rebooted and everything. And, Litchi still isn't working either. Any clues?
