You should have received an email and a notification with more info in Creator Studio. Take a look at those resources and note that you can always reapply for the YouTube Partner Program again in 30 days.
No, I've not. This information is given to me by the backend help team. When I mailed them 1 day after reapplying.
In the monetization tab, it still says "Under Review: Decision will be mailed soon."
@TeamYouTube please help review my channel soon.
