Cannot configure reverse thrust for any controller in MSFS 2024 for any aircraft

Same process on FlightStick for me. Same settings I used in 2020. Works perfectly.

Also the thread title is an exaggeration when you only mention two controllers. Probably better to use the forum to ask for help as a first step before adding to the deluge of “Operator error” non-bugs that are drowning the real bugs out.

I expect others have the TCA Quadrant working as well. If not there would probably be a bug already. Did you try a search?
