I've just tested the newly released "2.1" version of the A321neo and have found several problems with it. The same applies to the other Airbuses as well (I own the A319 and the A321neo).
Functional bugs
- The aircraft sometimes produces CTD while loading. This hasn't happened for me for a long time now. Also, the framerate can seriously drop from time to time, irregularly, but even while sitting at an airport. (Xbox Series X)
- On the aircraft data page, when you use the "Load flight datas" button, the flight plan is displayed in a very inorganized way. Screenshot: https://imgur.com/a/00slgrV
- The performance calculator doesn't seem to calculate the V2 speed. It gives V1 and VR but for V2 it says "NAN KTS". Screenshot: https://imgur.com/a/rrHoppR
- Upon loading the aircraft, the fuel and weight page has both sliders completely on the left side, despite the aircraft having both fuel and passengers/cargo on board. The page correctly displays the %, but the sliders are both at 0.
- The "Turn EFB ON/OFF" button doesn't work. The EFB cannot be turned off.
- The catering truck cannot be added on the ramp manager page, the icon doesn't activate and the vehicle doesn't appear. (I tested this on a ramp, not at a gate.)
- The "External power" button tooltip is reversed. When the button shows "Avail" (e.g. it's off, but available), the tooltip says "ON". When it's actually on, the tooltip says "OFF". Screenshot: https://imgur.com/a/Kc1KTN2
- The central pedestal system page buttons all show incorrect tooltips. They all show the one left of them, not their own. This is an existing bug, not a new one. Unfortunately it's still there. ENG shows FUEL, BLEED shows ENG, PRESS shows BLEED, etc. Screenshot: https://imgur.com/a/qog1SYo
