When you share a Reel from the mobile app, it gives links such as
https://www.instagram.com/reel/DTAcc_gE7J7/ (tracking parameters removed)
When you open this link on the web (you MUST log in first, sorry), it straight up does not work.
It will: first redirect to `/reels/` (with an extra s. both should work in general), and then it will either
get stuck on a white page and, for some reason, make my CPU fan run like crazy;
give up and just redirect to your reel timeline, i.e. a random video that is not `/DTAcc_gE7J7/`.
This does not happen for all Reel links, but for a non-trivial number, if not most, of them.
The only workaround is to manually change the link to `/p/{post_id}` and open it as a post (which has a different, worse UI because the video canvas is very small).
This has been broken for at least weeks, and I found people talking about it on Twitter too. But time has passed and no fix is coming.
