The former issue may be intentional. I've seen many recommendation algos not quite letting users shoot themselves in the foot. It's like how if you subscribe to 1000 channels on Youtube, it'll start only showing you the videos you actually watch instead of all the videos. The latter is strange, but generally for me it has worked pretty well, without even needing to rely too much on "not interested". For example, in March I started playing Animal Crossing, and a week later my feed was 50% ACNH content. Then I stopped playing around May, and a few weeks later, I was quickly down to maybe 1 a day and now I'm at 1 a week maybe. That being said, I like and share videos frequently, so that may be a good signal of what I'm currently interested in to the app.
