Admob error Video Rewards

Hello guys,
I have a big problem … my app contains banners and videos with rewards, when they click on an ad or watch a banner, the impressions on admob increase and I earn a few cents, but the problem is that I have clicks on the videos with rewards, impressions too, but that doesn’t pay me. I also tried with the interstitial screens but it doesn’t work the same, the advertisement appears but it doesn’t pay.
how could I do??

You should ask Google who manages Admob.
Or read their documentation, it’s super complete!

Randomly you might miss the bank details?
