Hi there, the majority of eligible channels hear back in a month or so. Note that all applications are still manually reviewed, so it does take a bit of time. In the meantime, here’s a bit more info about the review process: https://yt.be/help/YPP-review . Hope you hear back soon!
Know a majority of the channels that you guys will go in and look at don't even get reviewed because you don't think they have any content or you use an excuse stop telling people that they get reviewed in 30 days when you hold them out
