The autopilot has to be off.

The easiest way to disarm it is to “blip” the electric trimmer on the control column (see bottom right) or engage/re engage the autopilot.
In my example, I was assuming that the MCAS had kicked in after the pilot had switched to manual mode. So blipping the electric trimmer is a separate process to engaging the auto-pilot? I don't know much about flying passenger planes, I'm just trying to understand how the software works.
