I have been flying recently in an Authorization zone and I would like to share my experience for those who haven't got there yet. Unlocking best done on PC before the day with DJI fly safe, rather than with phone app on site. I request 1 day, but period given is 2 days - no problem flying. If you don't have the acceptance you won't get off the ground, that includes using DJI fly, Maven & Dronelink. My situation has been that an Authorization zone is usually close to a Restricted zone, so I have had problems when getting in too close to the latter while having clearance in the former. Getting a permit for a Restricted zone is a little more difficult for me when flying near a military airport. Coming close to the Restricted zone has caused my drones (M3 & MA2) to mess up and return home - see attached flight log of the M3. So beware of that one. My purpose was to map and photgraph real estate project in Medan Indonesia and only got 1/2 of it done. Note that there is a lot of data in the flight record -tells all.
