It took a while, but the page loaded for me in strict mode, though it reveals a "only available in the USA" screen instead of a request to put the device in landscape mode. I did see a request to disable my popup blocker, but it did not seem to break anything.

@Raul, does this issue still reproduce for you?

Thomas, after a couple of seconds/ tens of seconds, the "Disable pop-up blocker" request disappears, and the message to rotate the device is presented. So now, the page is not stuck in a loading/downloading state. But the top message is only displayed in Firefox, which disappears once the page has finished downloading/loading. I have used a VPN actively pointing to the US.

Tested with:

Browser/Version: Safari 15.5/ Firefox Daylight 100.1 (9384)
Operating System: iOS 15.5

Then this seems like it's probably iOS-only breakage, so I'll mark it as such.
