We'd like to know more. Was your channel monetized earlier and now demonetized, or is it the first time you've applied and were rejected? Also, please share your channel URL and a screenshot the monetization page: https://yt.be/help/acmo . Keep us posted.
Appreciate your patience while we looked into this for you. We've received an update from our team. The channel has been re-reviewed and the decision stands that it will not be approved for YPP.
