I think they've stopped updating this version of the website as we'll soon be using the "beta" (think that's the correct term) - the pages for conspiracies already work over there, but without the styling. Here's this page on the newer version, and the video container loads correctly there:

https://communities.win/c/Conspiracies/p/12kFZA4TvG/australian--trucker-exposes-main/c

hmmm...Even though I gave the correct link, it reverts back here. anyway, if you want to see the new site go to meta, https://communities.win/c/meta/new, which is only on the "beta" version now. Somehow I found my way to the conspiracies page on that version, and the video loads fine, but I can't seem to get back there now! Transitions can be messy I guess.
