I load the flight plan, then I requested refueling, the truck comes.
Then I click in the EFB GSX menu on the simbrief value, the truck drives away and nothing happens.
In the MSFS 2024 Premium Version of EGLL only GSX works.
Nool isn't supported anymore.

It isn´t a general Problem. Check your library and your content.xml that all other OMDB sceneries are disabled.
In my case these are 3 other OMDB aiports (Gaya, MSFS2020 Premium Version, MSFS2020 Deluxe Version)!!!
