I am having trouble learning how to upload my pinpoints on my DJI RC PRO controller.

I cant seem to find where to save them, or where they saved. I have watched many youtube videos, but the most helpful one seems to not work either. I tried going through the controller and going to files, Android, DJI, but then it the "PIN" folder doesnt exist, however the pins are still on my map when I turn on the controller.

is it saved on the internal of the controller? Or the drone?

Anyone have any Ideas?!
