DJI may have created a great product but their software engineers (I could use another name for them) just plain are idiots.... why just about when I finally figure out their latest way to unlock an authorization zone they change the set up.... it seems there was a short time when I could do it on site... and and the unlock would take about half the time but now it wants me to log in from the controller and I don't have a clue how to do that. I'm just venting here because I am so frustrated with a product that has great potential and I use in my work but is not cost effective to the time I have to invest trying to make it work. I wonder if they at DJI even look at this forum.
