@TeamYouTube please help.
A video on my channel has abruptly stopped serving any ads despite being fully monetised with green $$$ sign. 200k+ views and ZERO ad revenue. This video was doing perfectly fine only a few days ago.
About every few months we push system updates to improve accuracy. When this happens there’s a chance some previously green icons turn to yellow. If you think this is not the case, you can reach out to the Creator Support team as a next step: https://yt.be/help/partners
