Not sure that'd matter, but it only shows that if you're on a mobile device (phone, tablet), and only if YouTube is on the mobile URL (m.YouTube.com). On a laptop you might not see it. You want the URL from the browser and as "www.youtube.com".
The mobile link (m.youtube) may work in some places might work here if the embed video parser takes it... Doesn't on other forums I'm on (and didn't used to here, haven't tried it in a long time, just make a point when I'm on a mobile device to switch and get a www.YouTube URL since other sites don't).
Definitely avoid the shortened "share" link from YouTube though if you want to embed the video.
