Monetization Problem in Showing Ads

I have purchased a monetization app upgrade. Then I put only admob ads on my app. My app is live on play store and my admob account has been approved to show ads. But after I try the app, sometimes it shows ads other than admob. How could this happen? Does niotron take commission? Even though it’s been mentioned that niotron is committed to 0% commission

Nope, niotron doesn’t take commision in any way

It’s managed fully by Admob, you can contact them to ask the reason.

Are you using facebook adapter?

In bidding it happen usually. Dont worry you will get your income.

Admob showing his partner ads also some time
