Both features are broken. "Not interested" does nothing aside from temporarily hiding the video. It's not a signal for "I'm not interested in this category of videos". These videos keep coming back anyway and the problem gets much worse if the same content is uploaded to multiple channels. There are videos I've blocked at least five times "Don't recommend channel" is a cruel joke. It works at first but it gets reversed when you view a single video from that channel. There's no way to enable it pernamently. Sometimes I like certain videos from a particular author but dislike the others and don't want them recommended to me and I can't click on a video added to my favourites without reversing the channel block.
