A330 works on my end.
I still have this issue, only tried A21N. EFB says 5780 kgs of fuel but it loads 9080kgs.
Had the same problem in A321, should load 7700 kg of fuel, fuel tanks indicates more than 12000 kg Version number 6.31.0
I was flying A321 on the xbox yesterday, latest build 1.6.31.0, streamed aircraft, and there is still issue with A321 loading fuel. You have to use msfs EFB then it is possible to load./ change qty via Aircraft EFB.
I also took a few flights with A320 and long haul A330 and both these work fine (fuel loading and fuel consumption) but A321 isn’t. I understand this thread was closed but are you able to test it and try to replicate it. I did three A321 flights and all had same issues with initial loading of the fuel. (consumption is ok).
Still have this issue in SU4.
