Putting a link on its own line

So, apparently if you post a link as a line by itself, it’s supposed to create a preview box. I’ve seen other Dopers doing this, but I can’t make it work. Am I missing something?

I can still embed a link in text, but I’m not getting the single-line preview.

What’s up?

Evidently it’s turned off for YouTube.

Stuff above the link

Stuff under the link

It works for YouTube but you need to click on the SHARE button / “embed” and snag THAT version of the link—not grab it from the address bar.

Let’s see.

Hey, whattaya know!

Test

EDIT: so you have to click on the embed link in YouTube and then only paste the URL part of the code. That seems a bit of a faf but it works…

You don’t need to use embed. You can simply click ‘Share’ and copy the youtu.be URL.

e.g.

https://youtu.be/6CFNNldyI-0

I’ve definitely tried that unsuccessfully in the past but let me try again…

EDIT: okay that’s weird.

Looks like they’ve been fiddling with the board settings.

Which may explain this.
