Hello everyone.
I still have Msfs20 installed, from its Official folder I took the airport folders that I purchased from the Marketplace, and copied them into the Msfs24 community.
I start the sim, but positioning myself on one of these airports, only the default appears, as if it were not present in the community.
I have about 200 pay airports, and the problem only exists with those from the Marketplace.
Thanks to everyone.
