I live about 4 miles from an Air Force base and I am located in an Authorization Zone. I have a DJI Spark and I've gotten it to fly before around my yard. I went to fly it today and it won't allow me to fly it outside of my house. I have done all of the necessary steps to gain access, but it just won't let me take off outside. Please help.
