I have a controller that came with my FPV and it works fine with my FPV drone.
I installed flight sim app on my pc, connected to my pc. Used assistance app and its software is up to date.
I connect it to flight sim app, when I click controller pic on bottom right, it says the controller is connected but no green light. it's still greyed out and obivously, it doesn't work with flight sim app.

what is the issue with using my controller with my pc?
