Yup, I’ve done that several times.
For information, it does not matter how I assign/use flap selection method (either by mouse click/drag, keyboard key assignment, or throotle quadrant switch), the flaps only move between two positions - 0 degrees and 42 degrees.
There are no known control assignment conflicts.
As an oddity: when I try and use keyboard assignments (eg F6=Decrease flaps, with F7= Increase flaps), or I assign a pair of throttle quadrant switches (eg Joystick Buttons 5 and 6, to respectively decrease or increase flaps), only the first assignment in either pair functions, and then it only works as a ‘toggle’ flap switch. The second assigment in each pair is functionless.
If I use mouse click/drag on-screen, it too only allows two positions of flap.
I am wondering if I should uninstall then do a MSFS2020 re-install. I hesitate bacause that is a lot of work for a small issue.
