Hi Frans, if you haven't heard back yet, this 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 – our team doesn't have specific timelines for individual channels. Hopefully you don't have to wait too much longer for your update. Appreciate your continued patience!
