On the DJI No Fly Zones page at No FLY Zones | DJI I saw that there is a "height restriction zone" around "no fly zones" within 5 miles/8 km of a major airport. Has anyone flown inside these height restriction zones? Is the height really limited? I am still using firmware 1.1.9 but with the latest app, and I haven't experienced any height limit in these zones. Moreover, these height restriction zones were introduced way back in April, even before firmware 1.1.9.
