We review all applications carefully–if you weren’t accepted into YPP at this time, then check your Monetization page in Creator Studio for more info: https://www.youtube.com/account_monetization …. You can make any changes based on those details and always reapply after 30 days.
We give careful thought to every YPP application and each one needs to be manually reviewed by our team of specialists. Due to the high applicant volume, it’s taken us a while to review every channel. We’ve been sharing updates about this here: https://goo.gl/d2c2y9
