I am trying to show the rewarded video ads in ionic 3 using ionic admobFree native plugin. I am able to show the banner and interstitial ads but RewardedVideo ads appears does not show every time. Because RewardedVideo Ad appears sometimes that means I must be doing things right. I have tried to show the test ads as well but rewardedVideo ad doesn't show as test ad either. Is there some kind of setting in admob that is causing this kind of behaviour because I am not getting any error but errors. here is my code.
let adConfig: AdMobFreeRewardVideoConfig = {
isTesting: false, // Remove in production
autoShow: true,
id: 'ca-app-pub-3940256099942544/5224354917'
};
this.admob.rewardVideo.config(adConfig);
this.admob.rewardVideo.prepare().then((resp) => {
console.log('admob rewarded prepared', resp);
}).catch(e => {
console.log(e)
});
