Dear @TeamYouTube,
@Aron_Ra has published a video about evolution yesterday and there was no sign of it in my sub feed. Judging by the number of likes (10 vs the usual 2k), it's a problem with the video. Why is that and have you been messing around with the sub feed algorithms?
Oh. Issue solved then. My apologies, @TeamYouTube.
Great video as usual, though I found it on the playlist before it went up officially.
