Hello,
I asked this question over on the PMDG forum but I am posting it here as well, hoping Umberto can chime in and suggest whether it might be something on PMDG or on the GSX side of things.
The normal scenario is this:
1. Catering service was requested via the GSX menu
2. The service vehicles arrived, automatically opened the R2 and R5 doors and supplied the catering.
3. Once finished, GSX closed the door automatically without user intervention
4. The service vehicles departed
5. Catering service was completed
After 2.0.59 PMDG update, there appears to be a problem in Step 3. The doors are indeed closed by GSX automatically as soon as the catering is finished, but they immediately reopen, requiring a manual closure via the PMDG tablet. But even after manually closing them via the tablet, they immediately reopen again. And so, GSX cannot complete the catering service. The vehicles, thus, do not go away.
After manually closing the doors multiple times, eventually, the vehicles depart.
As I run the GSX Live Update multiple times a day, I wish to ascertain it is not a GSX update that caused this.
For now, the catering service does not fully work with the 777-300ER due to the automatically reopening R2 and R5 doors.
