Sir can you tell me my all video is created by me but YouTube already rejecting my channel for monetization another 30 days waiting now to reply so tell me which's video I should delete ,
The best place to check is your Monetization page in Creator Studio: https://goo.gl/CCi8jp . From there, you’ll see an explanation with links to relevant resources. You’ll also see the option to reapply from that page in 30 days!
