I had the problem constantly and the update fixed it. I am therefore very happy.
But I realized an important thing. I have several controllers: 1 SimMax.it Throttle Engine (Throttle, Pitch and Mixture), 1 Thrustmaster TCA Quadant & Add-on, 1 TCA Stick, 1 Saitek Pro Flight Quadrant (not realy used, only bound on mixtures 2, 3, 4, for fun stuff).
After this update, Flaps, Speed brakes, Mixture and RPM axes have returned to the normal and expected behavior.
I just had an issue with the throttle and I think it also depends on the aircraft being used as well.
Single-engine airplanes typically have their throttle bound to the main Throttle axis (with no number). This is what I had on the SimMax TPM. On the other hand, I had bound the Throttle 1 and Throttle 2 axes on the TCA Quadrant.
When I left the escape menu, the sync could be done at the same time on the positions of the TPM (main Throttle) or on the TCA Quadrant (Throttle 1 & 2). Depending on the used device, this could be a problem.
So I re-bound the TCA Quadrant first lever to the main Throttle axis and unbound the second one. Now everything is ok for single-engine GA airplanes.
I think we have to be careful when using multiple controllers. We need to deactivate the unused/ghost axes and check the possible conflicts.
Sorry for my “French” English. I hope I was more or less clear in this feedback.
However, the workaround of switching to drone mode before going to the esc menu is still operational for those who still cannot fix the problem.
