It does work, I just tested it.
Two things…
Firstly, you need to use the actual YouTube URL, not the “share” URL.
For example, “https://www.youtube.com/watch?v=TDfKRDYE3w0
” not “https://youtu.be/TDfKRDYE3w0
“.
And secondly, if your row doesn’t have any actual content, you’ll need to give the row some height by adding top and/or bottom padding to it.
For example…
Give it another go. If you can’t get it working, post a link to a live web page that displays the issue and I’ll be glad to take a look.
