I've just copied FS traffic and another vendors traffic folder from my FS2020 community folder into my FS2024 community folder. Beyond ATC works fine with them.
Got the Baron to work by disabling the new Inibuilds G58 from My library in the Marketplace under 2024 Deluxe content and then enabling the old Asobo G58 under 2020 Deluxe content. All seems to be working well so far.
@qwz020 We hope so yes, we've not had sight or use of the SDK as yet so we're unable to guarantee 100% that will be the case, but we're hoping that's the case.
