I have now. Thanks!

It just won’t work. Not even just putting in the URL will work, and I’m doing it exactly as it says: paste in the URL, make sure it’s not linked in the page I’m pasting it into. Tried it with link too, and that’s the only time it works how it should, i.e. giving a link on previews.
