@TeamYouTube I don't know what you guys did with the recommendation tab, but you keep suggesting me the same videos or videos that I have already watched, or videos that I have watched before months but put a tag "new" under it...really?
Just to confirm, have you already tried these steps: Tap the 3 dot menu > Not interested > Tell us why > I've already watched the video? Also, our Help Center resource has info on how to improve your recommendations: https://goo.gl/mwxH46 . Let us know if this helps!
