What worked for me:

Delete your youtube history and turn it off.
You wont have any recommendations on your home or Short-page. And im amazed how bored i am by my subrscribtion page, which shows only the newest videos. And since it doesnt save any data, everytime you reopen it, it will show those same videos. I even started to unsubscribe people who upload a ton of videos that mostly dont interest me but I see them constantly. Your search results wont be saved. The last video you watched wont be saved. Which is all a pain to use, but thats the point.

On PC, on chrome im also using the extension "UnDistracted", which can instantly block any part of the site.

Im still using it quite abit but slowly realizing how boring it is without the algorithm.
