I noticed a little bug in GSX when I have to use the stairs every time it counts that to me as a disembarkation, I run the stairs to come to the plane doors, I call fuel and the catering, but he is still disembarking when, precisely, I would like to embark...
And a 2nd chose when it's the stairs how to make when the boarding is finished that the stairs remain sticking to the plane as long as I haven't closed the doors? Because at each end of boarding, they remove the stairs and I find myself with the door open without stairs ...
I use the A320 FENIX otherwise with the gateways no problem works very well may be a small bug on the UI menu
Have a good day,
