This happened to me today. I was flying in a green zone but repeated tried to fly into a yellow zone. My DJI would not go forward with right stick full ahead. I switched into sport mode, totally confused by the MP's behavior, and it still would not fly forward into the yellow "Authorization Zone". It would however fly the other directions . . . . wierd.
Anyway I finally received the dreaded GEO warning message saying I needed to get a token via SMS message on my cell phone. Twice I completed the dialogue box to receive the "token" number, and twice I received the code. It said this code is good for 5 minutes. . . . . but no worries I'm thinking, because I'm gonna' punch in the "token" now.
But alas, just like the OP here, no dice. The software never asked me, nor could I figure out, while my MP hovered in the air up high, where to put the dad gum token code. Could not for the life of me figure out the place to input the code.
So I thought heck, I'll just turn off the GEO system in the menu of DJI GO 4, which I did. Just as soon as I did that I was not allowed to set a new home point, so I had to turn it back on.
Anyway, I was out of town in a place I wanted to fly on this beautifuly day, and I was flumoxed by not knowing how to fly in an Authorization Zone. Could not figure out where to put the token.
I don't like Big Brother telling me what I can and cannot do, and further, when Big Brother does tell me what to do and a process to "comply" and I can't work it, e.g. I couldn't figure out where the token goes giving me access, I got a little frustrated.
I still don't know how the darn thing works . . . .
