I recently acquired a Mini 4 Pro...and I have a question about waypoints ....I have seen a video that explains a lot of stuff, but he is showing how to set up a waypoints flight using the map on the controller....which seems ideal....you set it up and go to the site with fully charged equipment....no need to waste power while getting ready...that person also has his controller and drone linked during the set up.....the DJI (official) video makes no mention of being linked....what's the word from guys who have done this?...Thank you....Mark
