Update: Channels in many niche topics are reporting massive drops in views today; I've found that real-time views aren't updating when compared to simply clicking on a video and seeing how many views it has. I believe this is a glitch rather than algorithm shift. @TeamYouTube
I only have two shiny Pokémon videos and I can only see accurate numbers when I go into YT studio. For almost the first 24hrs, one of my videos showed 2 views on my channel and video but had ~20 in YT studio.
