If you can’t get TrackIr working in MSFS 2020, you’ll need to download the latest TrackIR game updates: Open the TrackIr Software…top left corner (white ball) of the software - download the latest game updates then restart TrackIr.

One very stupid thing I noticed, if TrackIR is not tracking while MSFS is loading (TrackIR app running but not wearing the hat or not in range) then it won’t be activated during that session.

@Codexus Excellent and best information ever: You must wear the hat when MSFS!

That was the solution to my issue. Thanks.

Just like DCS… they’re not smart enough to check at the time of usage, only at startup.
