If your channel was eligible and applied before June 1st, your application has been reviewed and you'll be receiving a Creator Studio update and email over the next few days. Here's more info: https://goo.gl/2icqfh
Thanks for letting us know. Now that the backlog is cleared, we’ll be reviewing applications much more quickly. So long as you meet the eligibility and program thresholds, you can expect to hear back in a month or so. Hope this helps.
