Why YSK: There is a recent update in Youtube that force user to turn on history to see videos in recommendation/home tab. You can get over it by turning the history version ON and then watch a video and make sure it’s shown in the History tab. And now you can turn off the History and you will still see the recommendations/home feed loaded with videos. So the key is to not clear your watch history in Youtube if you already have one and then you can keep history turned ON/OFF as per you needed.
Joke’s on them, I don’t want Youtube recommendations anyway. I just search for the stuff I want and subscribe to the channels I like. Besides, I’ve made my Youtube front page blank with CSS to avoid all the spam.
