Donovan Davis is DJI said he believes the fly app will be the app used going forward. His “thoughts” are obviously not a guarantee but it makes sense.I hope I am wrong, and Im only guessing here, but I think DJI are trying to separate hobbyist and prosumers from professional users, and that the division in DJI fly and DJI GO 4 represents this division. One group is supposed to be intrested in the boomerang and the meteor and the other of planned autonomous flights. Since you are alowed 5 waypoints for your hyperlapse the technology is there, but I suspect they want to keep the mavic Pro 2 and mavic pro 3 compare well against the cheaper air 2 by witholding lichi from us poor MA2 owners. like I said I hope this is not so.
I do think you are correct in that they will try to differentiate the models some for separation —sometimes with completely artificial limitations. I don’t think the app itself is how they do it, but feature available in the app for sure. SDK maybe.
