I created a simple app using Android Studio and I already published it, I downloaded it to a friend's device to test how ads work. These ads in my app normally load a SMAT_BANNER in the app footer, but when I preview in AdMob they do not dispute the clicks on the ads but the impressions, which would just be the ad loading to be viewed, apparently are counting correctly.
Ex: I have 20 impressions and there should be at least 50% of clicks, but there is 0.
