So @TeamYouTube removed Long Non-Skippable ads sometime in December and a lot of people have videos that have the same or simillar stats and if one is getting 100$ revenue for an amount of views, the other one would get about 30$ for the same amount of views/watch time ¯\_(ツ)_/¯
Thanks for the info. Just to confirm, have you already tried reaching out to our Creator Support team? If you haven't already, here's how you can do it: https://goo.gl/BxLi8H . Hope this gets resolved.
