How to re-request Unity Ads if the first request failed?

Imagine the player was not connected to the internet when Unity Ads was initialised.

How can I make the game re-request the ads at a later stage, when the player has access to the internet?

Like so:

if (Advertisement.isReady ()) {
// code to reinitialise or request again??

}

 

I have the same question please. Do I have to switch to another ad network if Unity ads initialize failed? or any solution working?

 

i personally put My Unity Ad Implementation class in the beginning (Splash screen) scene to initialize on start of game, and also i put it on the game scene.
and in the start i check for !isInitialized
void InitializeAds() {
if (!Advertisement.isInitialized) {
#if UNITY_ANDROID
Advertisement.Initialize (gameIDForAndroid, false);
#endif
#if UNITY_IOS
Advertisement.Initialize (gameIDForIOS, false);
#endif
}
}
So every scene in my game it checks if advertisments are initialized and if not, initializing it

 

i found issue.
test ads does not show.

Error :- Unity Ads show failed: Webapp timeout, shutting down Unity Ads
