A) GSX integration has been bugged since the first launch and still has issues.
The fuel loading is not automatic, you have to remember to select the amount from the menu after the truck arrives otherwise it wont work or breaks (if you miss it its over!)
The catering service should be requested at the same time as the fuelling to save time
On arrival at destination, GSX always says there are 'no passenger stairs' even when there is clearly a jetway
B) The enroute map does not display for anything other than DEFAULT, when you zoom in/out -> I thought this issue had been fixed before, but has now broken again.
C) The ACARS system does not send messages for PDC/CPDLC - another thread has mentioned this already
