Since you're application is in review, we suggest waiting so our team can review it and update you with the decision. All the applications are manually reviewed, so it takes time. In the meantime, keep uploading original content, as more the content to review, the better.
We understand how important YPP is to you. We're putting extra efforts and resources to come to a conclusion through additional reviews. It's taking longer than expected because of the number of applicants & the manual review process. Hope you hear back soon.
