Hmm that one is a mystery. You should be able to copy the text and paste it in a browser. Not sure why that particular link isn’t embedding on the app. Youtube vids should embed with an image and a “play video” link in the app, but this one isn’t for some reason.
Central: try it now. That’s a youtube video and the original link was a shortened link, which doesn’t embed properly. I changed it to the regular long link style.
