On my app users can create content only after they've watched a Rewarded ad from AdMob. So on Page level I've created an Action on PageLoad to "Load interstitial ad" (unfortunately that's the only FF option available for AdMob) with ad unit ID inserted. (I have the AdMob Android App Key inserted in my Settings. ) Then I have a button "Create content", which has Action attached to it, on tap "Show interstitial ad" before it proceeds to other actions. But no ad is showing up.
Would someone be kind enough to help?
