Some people watched video ads in my app. And I see that in my panel, but there is no cash for this.
Is that mean, that they should click on this video? But this is revenue Ad, when they got something for watching this Ads.
clicks are better paid. However you also earn from impressions. But only "7" impressions will not leave any cash.
Wait till you have more impressions and check again. If there is still nothing, there could be an issue.
