Which Flight Plan app will allow flights in Authorization Zones

[Tricky]

I have clearance from Clarence. P3P. DroneDeploy WILL NOT fly in BLUE authorization zone, no matter whose authority you have.
DJI GO App allows me to fly, but I need to fly Grids over 200+acres several times this summer. DJI GO does not (AKAIK) have this feature.
I am having trouble with GS Pro - getting "Please restart the app and try again" Error (-10, 1)

I have all the permissions but need an app that accepts flights in Blue Authorization zones.

Help? thank you.

I haven't had to use GS Pro or any similar app within an Authorization zone. Can't you just unlock with DJI Go, then open GS Pro and fly normal?
