It could be not having an account or some device/broswer/ azb site compatability issue. When I post a link the site will default it so you can have a preview but like 1/6 video clips can only be seen on IG directly or have no preview or anything. A small % of IG accounts don't want their clips shared so I'm assuming they are blocked unless you are viewing them on IG.
I repost clips onto my IG account before I post on here which you may or may not be able to view directly on IG without an account:
Using an easily visualized alignment as a "landmark alignment" and adjusting from there to the nearby actual alignment ("by feel") is how most aiming systems work.
