Unity Ads problem (statistics stand still)

First of all, sorry for my english.
I have a little problem with the ads in unity, i’ve check my statistics in the morning and now (18 hours later) they don’t have change at all. I’m pretty sure other people have download my game and play it.
Soooo the question is… i’m missing something? how i’m not seeing anything different even though i’m 100% sure other people download my game and they have seen the ads?

Visit this site and search for “Why am I not seeing any revenue, even with 100 impressions?”

Typically it takes 5000 impressions or more to determine the quality of the users you are sending. You will be getting revenue based on the quality your users and the impressions you are showing.
So you need more than 5000 watched ads to start earning;)
