I have 3 years old youtube channel associate with adsense. But first 2 years I was inactive. As I don;t have 4000 hour watch time my channel monetization turned off. But now I have 6000 hour watch time and already 1 month passed. My channel monetization is still under review. Another point I have one copyright strick. Now what can I do?
You may need to be patient a while longer. Google says:
We'll email you to let you know as soon as the process is complete. You can also check the status of your application at Creator Studio > Channel > Monetization. The process may take up to several weeks.
You also have to have at least 1,000 new subscribers within a 12 month rolling period in order to monetize your channel.
