We would recommend you that preload the ad and set up the callback event, since it takes time to load interstitial ads.
Call the method
ShowFullScreenVideoAd after successfully loading an ad.It is recommended to display ad after OnFullScreenVideoCached to enjoy better ad performance.
To further customize the behavior of your ad, you can hook into a number of events in the ad's lifecycle
Since the Interstitial ad is always referenced, the corresponding resource will not be released and needs to be released by yourself.
If you need more than one full-screen video ad, it is recommended to create multiple FullScreenVideoAd to manage the corresponding video separately. If only one is displayed at a time, LoadFullScreenVideoAd can be called after the first full-screen video ad closes to load the new full-screen video ad. Please refer to the demo example for specific usage.
