Thanks for reaching out. Just to confirm, were you a part of YPP earlier and now demonetized or is it the first time you applied & got rejected? Also, mind sharing your a screenshot of your channel's monetization page: http://yt.be/help/acmo ? Keep us posted.
Thanks for the screenshot. We see that your channel doesn’t meet our Community Guidelines & YPP policies and cannot be approved for YPP: https://yt.be/help/AsbB . You can make changes accordingly and reapply after 30 days. Hope this clarifies.
