Hi
From now and then this message comes up and actiully I don't know what to do about it.
The refueling is done, the tanks are filled and then this comes up and the whole GSX process gets block by the refueling. Fuel truck is still "in position"
Sometimes I had to fake new amounts of fuel, less and more than the actual. In the A320FBW that might help
I had this for many aircrafts, now with the A350 using the EFB GSX integration.
