You are not wrong! There is something wrong with the development version. The aircraft will not go into managed decent at all, no matter what. It’s been weeks like that and no one is fixing it!! No mention of the issue on their discord page. if they don’t fix it soon I Will go back to the A320 Neo v2 which has weather radar and RNAV approaches , and does not have that issue, don’t know what is going on with FBW.
