This means a significant portion of your channel doesn’t meet YT monetization guidelines and policies–based on your current channel activity. Keep uploading original content and building an audience – you can always re-apply in 30 days from when you received the decision email.
I made it but monetization is not activated. What should I do with my all previous authentic videos? Do you think it is fair if I delete them? Would you please re-evaluate my channel? Thank you. Kind regards,
