I had 3 missions with Litchi today. First two went great, the 3rd never really happened. All 3 were different missions. I realized that on my 2nd mission when I went up to 100 feet, went to upload it, I forgot to switch it to F mode to upload it...and it reminded me I need to do that. Upload went great, and a great mission. The third mission I went up to 150 feet, switched to F mode and got a "upload failed" message. I tried it again, and go the same thing. I was a little spooked at that point and just brought it back down. Now that it's safe on the ground again, I was wondering, is there a height/distance that you have to be within to upload the mission? I'm sort of hoping so, otherwise, I don't like things just not working. It makes me nervous!
