@TeamYouTube I have applied for YouTube/Adsense monetization about 7 months ago. There is a waiting list, which was first promised to be completely reviewed by the end of April. Then, said list was to be reviewed by the end of June. Still no reply. I am quite disappointed.
If you were eligible & applied before June 1st, then you should have received an email & update in Creator Studio with more info. If your application is being held for an additional review, then you'll get a second update in the near future! Latest update: https://goo.gl/2icqfh
