Using an iPad mini 5, and P4A, I am consistently unable to upload any mapping missions at all in the last 6 months. Is there a known issue/fix? Upload Failed is the error.
I use a very similar setup and was having the exact same issue as you it sounds like. Drone Deploy was unusable for almost 8 months until I finally got it working again a couple weeks ago. Let me ask you this where do you get your KML/flight plan files from? I was finally able to pin that down as the source of my problems. Hope this helped you as well….
