Can anyone who has the latest FW installed (1.6.4) please advise which NFZ it accounts for...the new 15-mile or the old 30-mile?  I ask because DJI has both of these on their NFZ page.  When I look at the No Fly Zone page, http://www.dji.com/flysafe/no-fly it shows the 15-mile NFZ.  
When I look at the Advance Unlocking page, http://www.dji.com/flysafe/geo-system/unlock it shows the 30-mile NFZ.
I fly within the 20-30 mile area and am afraid to update the FW if it won't let me fly.  Does anyone know which NFZ this new FW uses?  Thanks!!

there are some replies to this question on the Official DJI Owners  Group facebook page.

I live inside the Washington DC SFRA but outside the FRZ and both the P3 and Inspire fly just fine.

AND B4UFly shows no issues with flying here.....

I am right outside of the 15mile ring and cannot fly (grounded due to DJI GO App says cannot take-off). Am I doing something wrong? I even went to the Unlock Geo Authorization Zone and it still have the 30mile restriction. Even though FAA changed this recently: http://www.faa.gov/uas/no_drone_zone/dc/

Any help is appreciated. Thanks
