Thank you.

When requesting playlist items youtube-dl is missing several most recent videos compared to the actual youtube page. Some hours old. This happens on several youtube channels. Is there some sort of delay?
youtube-dl --playlist-items 1-3 -j --flat-playlist https://www.youtube.com/user/NHLVideo/videos
