I have a platinum that am using NLD on it but it won't do waypoints, the app supports it but when it tries to save to bird it fails and NLD says it because of the firmware on mavic. My understanding is that every firmware become more and more restrictive and the dji go app requires login/faa tracking etc. Only things I'm looking for it no tracking, no login, waypoint support, need to be able to fly at least 4000ft away, 400 ft height limit is fine. Since my current firmware on my mavic won't support waypoints does anyone know the lowest one that will support waypoint and not restrict me. I've never updated because I know they kept restricting and you can't downgrade. Any help would be appreciated. Thanks
