Also @lixus98 (not sure how we mention each other here) I get around the YouTube algorithm feeding me junk by never using the app, I just view in browser (Kiwi on mobile) with uBlock & SponsorBlock plugins & another for background playback. For subscriptions & any vids I want to watch later I add links to a note taking app which syncs to all my devices.
A little more effort than using the app but for me worth it not to be continually bombarded with recommendations for something I accidentally clicked months ago!
