InterstitialAd.load
Load the interstitial ad.
Return Value
Promise<void>
A resolved Promise only means the load call was accepted; it must not be treated as "loaded successfully". Load success is reported through onLoad, and load failure through onError.
load() is rate-limited (currently triggered by repeated requests within 10 seconds). When the limit is hit, onError() returns the error code (errCode) and message (errMsg).
Example
javascript
interstitialAd.load()
.then(() => {
console.log('Interstitial ad load call issued; waiting for onLoad');
})
.catch((err) => {
console.error('Interstitial ad load call failed', err);
});
