Very nice improvement and I hope more fediverse software starts supporting this. tl;dr popular videos are also uploaded by the viewers, thus lowering the server load, similar to Bittorrent, but all in the browser.
I thought I'd try and login to see the new update that @ernest has been talking about but it seems not only have I been logged out but I can't login as when I go into the Login page it just goes to a page saying '404 page not found' is anyone else having that issue?
