Can someone please share some tutorial about the AdMob interstitial ads? There is only 33 second video about interstitial ads:
But it doesn’t clarify how the interstitial ad shows up as a popup over the screen. Because in my case, I placed the interstitial ad as advised under the actual content on the screen, but it doesn’t popup like in the video. In fact, it just shows up like any other banner ad.
Please if someone can share some tutorial/video about it, that will be very helpful.
