Did LingQ change the embedded YouTube player from "youtube-nocookie.com" to "youtube.com"?

Did LingQ change the embedded YouTube player from “youtube-nocookie.com” to “youtube.com”? Is it a bug or a permanent change?

A few hours ago, the embedded player’s link was changed to the “youtube.com” style one. Is it intended work?

I am not familiar with any change, but I’ll check with our team to confirm. Are you experiencing any issues?

It is no matter. Just a curiosity.
With the “youtube.com” player, the videos show up in YouTube’s watch history.
