I am not sure that the entire 2024 community is facing this issue. I am not. I do see that the sim itself does take (Sometimes) a very long time to exit to the desktop (That does need a large dose of patience) BUT I do not see this as a major issue. Nest time you load up the sim, ie. streaming, all is OK and back to normal. ? right?
In summary, not so sure that even if you get the same issue on your setup with the A350 in 2024 you intended to exit the sim right? and simply close down in task manager if it has frozen ?
The key takeaway was your comment quote "purchased FS2024 and noticed that all iniBuilds products work fine" -= Happy days!
