The last couple of times I tried to us Litchi, I've had some weird problems. Those wer also the first times using it by the way. The first time, I started up my drone, opened the litchi app and started a pre-defined course. The drone suddenly decended quickly and bounced itself off of the grass, then started the mission. I hope that didn't damage anything. The second time, I started from an off and landed position. It took off and headed in an unrelated direction to the set course. I had to switch to P in order to stop it. Then I did a firmware update that I noticed was available. After that, it behaved strange like the compass wasn't calibrated so I calibrated that and it was better. Then restarted, launched with DJI Go, switched to Litchi, and started the mission and it went fine. I restarted again, started the mission before launching and it went off in the wrong direction. Then I restarted again, launched with DJI Go, switched to Litchi and started the mission. It performed fine until the last of four points and went off in that same wrong direction. I had to switch to P and bring it back. Am I doing something wrong?
