Can't Change AP pitch

@Martyn
With the GNS 530 NOT selected, I still have issues with pitch modes.After takeoff setting AP on and controlling pitch works fine.
Having an altitude selected, makes the AP switch from Pitch to HT, but while it tries to level out, it keeps climbing through the set altitude.Changing back to Pitch mode, the stabiliser seems to be stuck, and I can no longer change the pitch - the elevator trim wheel simply snaps back.
I have tried to disable the WT GNS 530 in the Panel.cfg file, but with no change.
Edit:
On my Stream Deck I can monitor the in-sim (Asobo) Autopilot settings.When I engage the F28 AP, then the following in-sim (Asobo) AP functions are set to ON: AP Master & Level mode.
The F28 AP shows Roll & Pitch, and I can set the Pitch with the switch on the Pedestal or by pressing the V/S Inc./Decr. switches on my Stream Deck.Once the F28 comes close to the Altitude preset, the in-sim AP changes to V/S and the V/S value decrease until it reaches the set altitude, where it changes to ALT hold mode.
But the F28 just keeps climbing and the Elevator trim wheel seems to be stuck, or rather snaps back to it´s initial position when I use either the Pitch switch (or V/S Incr./Decr. switches on my Stream Deck).I wonder if any 3rd party addon can affect the AP.
I have alot of Aircraft addons, but most uses the standard (now WT) GPS units, PMS 750 or TDS GTNXi.Edit 2:
I tried to disable all my addon aircraft in the Community folder to rule out any incompatibility with any of those , but to no avail. -
Just a thought...
Could the PMS GTN750 or TDS GTNxi 750 cause Autopilot issues ?
Also - is the F28 using standard MSFS AP functions, or are some of them custom coded ?
The reason is that when I look on which MSFS AP functions are actve on my Stream Deck, I wonder why the LEVEL mode always seems active.
Also when I use IAS mode, once I get near the Preset altitude, the MSFS AP switches from IAS to V/S mode with decreasing V/S as it comes closer tol the Preset altitude and then goes to ALT mode.
But while the MSFS AP indicates to be in ALT mode and V/S is set to 0 ft/min on my Stream Deck, the Aircraft keeps climbing. -
@wothan Yes, the autopilot uses custom code in the process of leveling off towards an altitude capture, both in PITCH and IAS modes. This is to smooth the capture form an otherwise different behavior with or without GNS selected. However, once altitude has been reached, the AP is totally controlled by MSFS ALT HOLD mode. It seems in your case there might be some controller mapping issues. We are going to investigate that.

Note that I´m not using any controller for the AP other than AP ON/OFF Toggle on my Yoke and the V/S Incr./Decr. on my Stream Deck.
In the start I used the blue Pitch switch on the Pedestal, but with the same issue.I have only tried the F28 4000, and will try one of the other versions this afternoon.
So I´m pretty sure that this isn´t a controller mapping issue, but rather some backround app intervening - or a F28 bug.

I'm having some problems with the AP
-
When I select GPS the autopilot is not able to sustain level flight. For example. When I select FL 280, the autopilot passes that level and I have to play a bit with the yoke so that it can be more or less close to the level of flight that I want. but it's hard to fly like that.
-
It may be that sometimes I select the type of flap and the V1/Vr for takeoff in the first officer's panel (I'm investigating)
-
It could possibly be due to a tail strike, sometimes the winds are so strong that I hit the runway gently and this can happen (I'm investigating)
all this could be a coincidence or just my F28 sometimes doesn't like to fly lol

Have the same issue here...
There's a fix or not yet?
-
Thank you guys ! With the 1.2 there's no more issue with the pitch !
-
I beg to differ... this version did not fix my AP pitch issue.
When the AP is in pitch mode, the pitch trim does not respond correctly to changes from the AP pitch trim switch. When the switch is activated, the pitch wheel will move as directed, but when the switch is released, the trim wheel will move back to where it started. This is the same for trying to change pitch in either direction.
What gives? I am open to being better educated about this if necessary, but I'm really surprised this wasn't fixed. See posts 3 and 4 in this thread. That's still the problem.

Hi,When you keep the PITCH INC/DEC switch constantly pressed, does pitch change? Let's say for example you are flying leveled (0 VS) , set PITCH mode, hold switch INC position until vertical speed reaches 2000 ft/min, then release the switch and vertical speed returns to 0? Pitch trim gauge & wheel perform a bit different with or without GNS enabled, but it should not affect the target pitch (VS) you are selecting.

@taguilo Yes, the pitch is changing as commanded with the switch, but the wheel always goes back to where it started.
I have never used the GPS with this airplane.
I will consider myself better educated, Taguilo, and go on about flying! Thanks.

One more piece of information... I just did a short flight where I took off and engaged AP at 2000 ft. , climbed to FL180 at 280 kts, then descended for landing and disengaged AP at 2000 ft. and 180 kts. The small pointer on the captain's trim wheel never moved from the C in "climb".
