Go to the subscribed page and watch the channels you subscribed to. The home page is whatever YouTube is pushing you to watch - it’s not necessarily what you want to watch…
Yeah some people never do that for some reason. I have a simple little tampermonkey script set up to automatically just redirect me to my subscriptions when I go to the home page on accident.
Funny, for me it's the opposite, I hardly ever set foot outside of my subcriptions page except for searching, which is how I find new channels to add to subs.
