@TeamYouTube couple of questions. What happens to all videos that were created before monetization was enabled/approved by you? Also, what is the average time frame past June 1st, one can expect to wait once hitting the 1000 sub 4000 hour threshold.
It seems that they're approving people in waves, at various intervals throughout the year. Unless something has changed, you just need to enable monetization on any video that is eligible, regardless of when it was uploaded.
