Hello Umberto,
I know this is an OLD Asobo bug. But in the meanwhile is it a workaround ?
I have noticed when we use in the menu Deborabing/Boarding if we change the zoom in the external view, the jetway retracts and stay retracted. ==> I have to restart GSX
But:
If I use in the menu Operate Jetway (so there is no passengers) (to the aircraft) and if we change the zoom in the external view, the jetway retracts BUT if we zoom in again the jetways it still extended (connected to the plane).
So in conclusion there is maybe a workaround we should use with the onboard/deboard functions like operate jetway ?
