Thank you for reply,
the issue is just upcoming with the AS Bus. Regarding AS the bus is now since version 1.2.2.0 100% compatible with GSX2.
Indeed he does all what we expect , open cargo doors close doors etc. The only thing he doesn't is counting up the pax/cargo in the load section of MCDU3 during boarding.
In opposite to this he count down the pax and cargo during deboarding, as you can see in the picture above.
