If you haven’t heard back yet, this means the team didn't reach a clear decision during the 1st review, we’ll put more effort/resources into the final decision. There’s no way to expedite this, recommend reviewing our YPP Policies and more here: https://yt.be/help/YPP-review
Sorry to hear you've been waiting so long. Unfortunately, our team doesn't have specific timelines for individual channels. Hopefully you don't have to wait too much longer for your update. Thanks for understanding!
