Thanks for reaching out. Your channel is still under review because of the number of applicants & the manual review process. We recommend uploading more public & original videos as the more content for us to review, the better! More info: https://yt.be/help/AsbB
While we don't have specific timelines for individual channels, we're reviewing as many applications as humanly possible. Our review team are on track in sending out the remaining decisions soon. Hopefully you don't have to wait much longer for an update.
