I just checked the AirMap website, and boy am I glad I reside far, far away from regulated airspace. The notion of yet another regulatory body offering to chaperone drone fliers for a fee, does not sit well with me at all.
I wonder if the OP would consider bidding a fond farewell to AirMap and other similar Big Brother entities, in order to fly with Litchi, thereby assuming all rights and privileges implied or presumed.
I have the same situation in Lansing, Michigan. I am a 107 pilot that has used Airmap several times in the past. I have sent at least 5 messages to Support and Contact Us with no response. Anyone know what's going on here. I was able to get my FAA approvals via Skyward. but it's a new system to learn. (Have not got Skyward figured out yet but that's my fault.... needed approval to fly a mission and fumbled my way through to get an approval.)
