Hello @TeamYouTube - I know you're busy but I've been in monetization review for 6 full months now and this is after my account for review was bugged for 4 months so in essence I've been waiting to be monetized since May 2018. Can someone help?
@Youtube, please add an application declined notification. Its not fair, its not acceptable and its not professional to leave people's livelihoods hanging on a "application in review" message for months. Hope this can be considered in the near future.
