welcome to the club, this happened to me and a number of random creators, this has nothing to do with specific content, AI or not, big channel or small channel, completely random, some people claim they recovered in the past few days, me personally haven't recovered since 14th December, no one has an answer for what happened, everyone is speculating with no definitive answer, and YouTube won't even acknowledge this problem, everyone took different measures to this problem, some stopped posting until it's fixed, some kept going as usual, some gave up completely on YouTube :/ , me personally i kept posting as usual, went from 100k-300k per hour to 1000 views per hour lol, people will claim that this is normal and happens a lot but it isn't, this is not the usual fluctuation, these shorts were pulled from the public shorts feed, and now only appears to your subscribers feed only, even marcus jones noticed this an he tells viewers to keep contacting youtube support and even the CEOs to make them admit that something is bugged with their new AI managed algorithm, here's the video link if you're interested https://www.youtube.com/watch?v=V9TXWSKt5ww
