Sorry for the delay. If you've been waiting that long, your channel had a first review but we didn't come to a clear decision, so extra effort & resources are going into more reviews. Creator Studio doesn't show this, so it's confusing & looks like you haven't been reviewed.
This means our review team has not come to a clear decision during the initial review, so we’re putting extra effort and resources into reviewing your channel multiple times before making a final decision. Hope you hear back soon.
