Is YouTube embedded playlist broken?

It appears to be broken on our sites. Generating embed codes for any playlist shows an error for us. To get it working on my site, I had to replace "videoseries" in the URL with "playlist" (no quotes) and then it worked. Really strange issue.

Yes it's broken, but then it's not. You can literally change 'videoseries' to anything else and it will work. in fact, you can have it like this and still works: https://www.youtube.com/embed/?list=YOUR-PLAYLIST-ID

That didn't work for me, alas. But adding a random query parameter did: https://www.youtube.com/embed/?z&list=YOUR_PLAYLIST_ID

Yupp, it is working, thank you :)

Yes, super-strange but the subbing of "playlist" worked for me as well.

Super-strange but the "playlist" trick worked for me, thx.

yeah that worked for me. wtf yt?
