Cannot connect to Apple Store on iCloud on Windows PC

I am trying to download Keynote from the Apple Store on my Windows 11 PC.

When I am logged into iCloud, and search for Keynote, I click the link to the following page: Keynote - Compatibility - Apple

I then click the Download button, and then displays the Apple Store icon and the message "Connecting..."

And it then sits there until the cows come home…

I have tried on 2 browsers: Microsoft Edge and Opera, and the same thing happens on both.

BTW, I was unable to connect to iCloud on Windows after a BIOS update, but was able to fix that problem this morning, only to run into this problem now.

My initial goal had been to convert a Keynote file to PowerPoint, so I can see it on my PC. I was able to do that using ttps://www.zamzar.com/. But it's still ridiculous that I can't connect to the Apple Store on my Windows PC, which I'll need to do the next time I need to download something.
