I discovered today that:
As I checked the MS Store for the version update - nothing appeared to download.
When starting the FS, it was showing in the FS-Store that the US update needs a different version.
I quit the FS, opened MS Store and there was now the latest version available to download.
After finishing downloading, starting the FS, it gave me the actual US downloads.
I have not run it for a while and maybe it needs the game itself to check before the MS Store App download is triggered?!
