Hi folks, I fly under recreational rules. My home is 5 miles from the center of a regional airport at the edge of the corresponding restricted zone. Until now when i took off, a request for permission was offered. I always said yes and recieved permission. Recently at the same take off point (my back yard) I was asked for my phone number to recieve a code which when input would generate that permission, but the text never comes. You only have 60 seconds to input the code. Anyone having a similar problem, or better yet a solution?
