It seems to be working now in General Chat, however a new problem cropped in the Poodle Pictures > PF Monthly Photo Contests subforum over the past few days.
In this thread for the Sept contest entries, only the links would show. I assume members would cut & paste their YouTube video link, but it would show up as one of those youtu.be links and not show the video. I was able to go in and edit those links which you can see on those video posts, but ideally their contest videos should simply show up.
Please check if that subforum needs to be reconfigured for YouTube so it won't be a problem for next month's contest.
youtu.be links are usually from mobile devices.
I believe if you copy and paste the link on the desktop, it'll show as the full link?
youtu.be links aren't showing up videos? If so, grab me an example and I'll have a look into it
