I'm unable to get the autopilot to follow the flight modes I've selected. The airplane will roll through selected headings, nav courses and climb and descend through and away from pre-selected altitudes despite showing ALTS CAP. I have the IRS set to FMS. Multiple tutorial videos were unhelpful and no discussions on the Steam forums were solved. If I am unable to use the autopilot I will be requesting a refund. Thank you for your time.
