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/4DGA7r
We don't have an exact date or time frame, but the review will happen in the near future. In the meantime, keep uploading original content as the more info/content to review, the better!
