Anyone else experiencing issues with autopilot (touch screen, not interactive cockpit)?
After cruising for a while, when I try to descend, the autopilot keeps overriding my input and resets the descent rate to 0.
In case it matters, I'm flying a routing I manually set. The autopilot also has a cruising altitude set. Also flying the Boeing 737-900, I'm not sure if this applied to other aircraft.

The autopilot shouldn't do this, the copilot might.
Are you using the autopilot in the virtual cockpit or the copilot menu overlay on screen?
Can you please record a short video for me or post a couple of screenshots so that I know what is going on?

Virtual cockpit from my side.

Which buttons do you press in which order and at what point in flight?

For example at takeoff, when I choose the Vertical Rate and I enable LNAV.

I don't know if it's linked of not, but when I was doing my Paris Dubai flight, while approaching the descent waypoint, autopilot suddenly turned on left, but I touched nothing. Here is a screenshot of my flight.

What is very strange: Why are none of the buttons or lights on the panel illuminated? Weird.
Anyway, it appears that the autopilot is still engaged, please not the green highlight on the control on the screen.
The current autopilot mode is also displayed on the primary flight display, in your screenshot it shows "CMD" which means the autopilot is actually engaged. The autothrottle mode MCP SPD also shows that autothrottle is active, even though the light in the MCP is off for some reason?Do you have other lights in the cockpit such as the speedbrake armed light above the navigation display or any lights in the overhead panel?

I'm talking about the copilot menu overlay, sorry I mixed it up.
I'll see if I can get a video over later.
I found a workaround, when I use the virtual cockpit to set my descent rate, it worked.
