Recently my channel submission for monetization is disabled due to Reused Content. All of my videos are my very own content. But I think, this has happened due to one of my videos,that has already been uploaded in my old you tube channel. But I didn't noticed that. Now I deleted that video in both of my channels. But this is my assumption.
Am I right about what I am thinking?
Is there any way to identify the root cause of the problem? or if any other before reapplying for monetization?
Please help me on this issue.
