There seriously needs to be a reason as to why a video gets demonetized. @TeamYouTube @YouTube Suggestion: If a video is being manually reviewed, have the reviewer AT THE VERY LEAST leave a reason as to why it's being rejected. How are we expected to make our content better?
Wouldnt you be able to talk with your manager from YT? They should maybe give insight on whats going on. You can get demonitzed for stupidest things.
