I occasionally use DJI GS Pro but every time I use the app, I have to always first go into DJI Go app, before I can fly, and set maximum distance on (8000 m). It's like that setting in DJI Go doesn't stick. Anyone else experience this issue?

I would recommend you disable the Distance Limit directly if you want to set the maximum distance on 8000m. Besides, have you clicked the “Done” on the keyboard input after you typed in the number 8000.

Ummmm, if I disable the distance limit directly then DJI GS Pro won't fly until I turn it back on and set some type of distance.  I always click "done", it just sticks.  Apparently I can fly the drone under DJI Go with the distance off, but not under DJI GS Pro.

I actually meant to say it just "doesn't" stick when I make the change to max distance.
