If you haven't heard back yet, this usually means your channel is being held for additional reviews (bc your content is close to not meeting policies). We’ll put more effort/resources into the final decision, thanks for your continued patience: 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 (thanks for understanding). Hopefully you don't have to wait too much longer for your update.
