I have been documenting a construction site for several months. This location is shown to be within a 100' altitude approved area by my AirMap app. When I started the project I had no issues. However, the last several times I have visited this sight the DJI NFZ would not allow me to fly. Typically, before this issue started, I could clear the NFZ by pulling back on the sticks to engage the rotors. I would then receive the option to request a certificate to fly. I would make the request and the NFZ was cleared. Now I get this drop-down menu. The United States is already filled in. The next request is for my cell phone number. When I enter my number the United States location is cleared. I then have to scroll all the way down to the US and reselect. This selection then clears the phone number I have just entered. It is an endless circle jerk! I also went into the app to refresh the licenses which the app claims were successful. However, the red NFZ indication remains. I have submitted several requests with DJI support to resolve this matter but thus far with no reply. Any suggestions?
