I appreciate any help you can provide. Top left in the app reads Altitude Mode and Fly Spots. In all the videos I have watched this reads GPS. When I click on fly spots it reads 0 Available. I have read the ops manual but did not see anything. It flys fine and the return to home works but as a new drone pilot I want to ensure it is set up correctly before I fly it too far. What do I need to do to get this to GPS mode? Thank you.
