Can someone outline the procedure to fly with permission in Delta airspace? I can get Verbal authorization from ATC, but DJI won’t release the DJI Go app to take off! I think I verified my account with my phone, but get the message - “Cannot verify account.” What am I doing wrong. I need to take 3 stills of a business facility from 100 AGL. Take about 10 minutes. About 2 miles from Regional airport. Help?
