I received LAANC authorization to fly today in Class D airspace and tried to launch my Mini. When I did so, a red box showed up at the top of the screen saying GEO Zone. I tapped on the box and up came a pre-flight checklist and an unlock opportunity. Even after unlocking, the DJI Fly app said the drone was unable to fly. It flies just fine a mile away at my house. Any insights on this GEO Zone issue? Thanks.
