I know others have reported this behavior but I honestly do not know why you and they get this. I have flown the A23NX many, many times and I have never seen this. I don’t know what we are doing differently. Without detailed information of your entire process, or sitting in your room watching what you do, I don’t think I can help. There are many many YouTube videos of people like Easyjetsimpilot, 320 Sim Pilot, CptCanada, XP72 and others flying the A320 successfully. All I can suggest is you watch their example.
