As all of you I’m also having trouble with the A320 and the AP. Trying to get around it by using the latest devmode from FBW, but every time I ends up with an AP that is not usable.
All this have made me frustrated, but at the same time it opened my eyes to do something I haven’t done yet in MSFS. Fly the A320neo manually. Not only at take off and 3 seconds before touch down, but all the way from point A to point B. Use my stick to follow the path, to get my plane to the assigned flight level, to get aligned to the localizer and glideslope. Adjust my quadrant to make sure I don’t overspeed or stall. I have to admit… It was really fun!
I’m not trying to undermine anything or anyone, just focus on the half-full glass. Happy flying!
