It’s been active for several months now.
Have you heard of anyone complaining that someone Junior to them was awarded trip 123 that they had asked for?
Have heard the current software takes a trip availability snapshot prior to the window opening and doesn’t update for any trips that subsequently become available.
In this day and age there’s no reason the system can’t refresh other than a program limitation. If you really need to program a last update time, should be say 24 hours prior to the SWW window closing
