Just had this in an old comment of mine
Some had hearted it just today, and so I went to see what it was about, and I could only see the text, no video previews.
So, first I did was to click the edit pencil, then I added extra empty lines in between, then saved, I guess this forced the forum to update the video links because now I got previews.
But it turned out that the 2nd video preview that should’ve shown the Karaoke version only showed the YouTube error preview … that video wasn’t online anymore … so a nice side effect was that I had the opportunity to exchange it with another.
