Based on the feed back from many different YouTubers now @TeamYouTube!
YouTube is infact broken. Notifications are not working. And people are getting recommended videos that are two months to two years old.
Youtubers are experiencing a 20% to 30% loss in views.
I keep getting videos in my recommended feed that are like 9 to ten years old, I got one that was 12 years old a couple days ago as well, and also the MF notifications always say scheduled digest now for some reason like to YouTube.
