I've been trying to monetize my channel for a few months now, and I'm at a complete loss. See, I made some audiobooks which got over 10k views each, and put me well over the requirements for monetization before I realized that's against YouTube's guidelines, so I deleted them, but my other videos still had over 4k hours of watch time collectively. I've gone over my other videos and they all seem advertiser friendly, and since I still have the requirements (albeit just barely), I keep getting my application denied. Is this because I deleted my best-performing videos? Or why could this be? Please help me out, I'm getting weary with the lack of communication YouTube is giving me.
