I am trying to fly at a convenient site that is within an Authorized zone. I am getting the GEO Zone red alert sign in the upper left screen of the Fly app and am not being prompted to unlock the zone. I have been trying to unlock the GEO zone in the Safety section of the app and it tells me that the unlocking license has expired and instructing me to go to the DJI website>Support>Fly Safe>Unlock a Zone. When I do that it only gives me the opportunity to unlock a zone for three days. It asks me to select the location and to input the flight controller serial number, which I did. I did manage to get that zone unlocked for three days. Is it really supposed to be this difficult? Thanks.
