We would like to know more. Could you please send us a screenshot of the monetization page from Creator Studio: https://goo.gl/ySjhEs ? We'll take a look.
But I have uploaded over 100 videos how many more are needed for the review to finish I have seen many channels getting monitzation enabled with less than 30 videos So why is this not the case with my channel any particular reason behind this or am I doing something wrong ?
