I just tried out Litchi with my P3S. I'm using the Dell Venue 7 running Android ver 4.4.2 for a display. I am getting a "Cannot run mission due to internal error" message. I've tried creating waypoint missions internally and with the mission hub, same problem. I have reinstalled Litchi 3 times now, uninstalled DJI Go, made sure that DJI Go isn't running, rebooted the tablet and I still am getting this error. Any help would be appreciated. Love the app so far though!
