A large share of short-form video clips (the kind shared from external hosts) were failing to load — you would land on a post and the video just would not start.
We tracked it down and fixed it: those clips now stream through their reliable playlist instead of a broken direct link. In testing, a feed that was previously littered with dead videos played start to finish with none failing.
If you browse video-heavy feeds, it should feel noticeably smoother.
