Hi, I cant get my GSX to come up for gate information once I land at any airport. Is there something I need to do on my part? I have the most recent update from the manual link here in the forums, then update GSX from the app afterwards.
What you could check is if Couatl is still running..

This happens for me too almost all the time. When I then hover with my mouse over Couatl in my tray (taskbar next to the clock) the Couatl symbol just vanishes. I then have to start Couatl manually again. Happens since one of the last updates I guess but I alway forget to check the log.
What might have helped (I have to re-test it to validate) is to close GSX (via the ingame menu, so that the icon is not highlighted) after departure or pushback and then to just start it during approach (once you're below 10.000 ft, before it won't open as you're too high). After that Couatl kept working, but I'm not sure if this is just a coincidence.
