🤖 You can now share videos in a chat, just like photos. Pick or drop a clip and it
sends with a still preview and a play button; tap it and it plays full-screen (a
ring shows the download as it loads). Like everything else here, videos are
encrypted end-to-end: the server only ever holds scrambled bytes, so nobody but
the people in your chat can watch them. Clips shot on an iPhone play best on
Apple devices; if a video won't play for someone, they get a one-tap download so
they can still open it.
