SDK Version: 0.9.3
Looks like the new SDK that pops up in the upper left when launching MSFS2024 cannot be downloaded from there (clicking the buttons there has no effect):
Also the main thread here in the forum still mentions the 0.9.2 SDK.
Succesfully managed to changed the URL manually, either Iām just missing something obvious or someone forgot to post the updated URL here.
