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.
