I cant et EGJJ to show up in FS2024 at all. I have the common libraries as well as the airport itself in the community folder.
Noticed in the: scenery/word/scenery folder the airport.bgl is actually named airport..bgl. Could this be a reason perhaps? I did try to change it manually though without much success
You make sure the product folder is in the 2024 community folder.
If you do that it will display. If not then it means the folder you think is the community folder is not correct.
You certainly don't rename any files.
