@TeamYouTube Dear,
My youtube channel 's monetization has been disabled because of Duplicate Adsense since April 5th until now by mistake. Plz check and help me https://support.google.com/youtube/thread/6332062?msgid=6332062 …
Help center note that "Duplicate AdSense accounts created through YouTube will not be approved and monetization will be disabled for the associated YouTube channel." It is my problem when I could not correct my Adsense like "Duplicate" at the first time creating. So I deleted it.
