MAX Interstitial Ads never filled, but AppLovin Interstitials working fine

MBornemann commented 2 years ago

MAX SDK Version

11.4.3

Device/Platform Info

iOS 15

Current Behavior

While implementing the iOS SDK to display MAX interstitials ads in our app, we have been stuck with production ads never being filled for a week. Every load attempt ends up with a 204 error despite having AdColony and Meta on top of AppLoving as bidding networks. Not a single user has seen a MAX ad.

The AppLovin sample app shows the same behavior when using it with our SDK key, bundle ID and ad unit identifier
Every steps in the documentation have been carefully followed
app-ads.txt is properly setup
Everything in the debugger tells us the integration is correct. Force loading an app through the debugger is working, loading an ad through the app won't
Showing ads through AppLovin instead of MAX (using ALInterstitialAd instead of MAInterstitialAd) is working as expected

Expected Behavior

MAX interstitials load request are filled and ads can be displayed to the user.

How to Reproduce

Use our SDK key, bundle ID and ad unit identifier in the AppLovin sample app.

Thanks for reporting this @MBornemann - we'll take a look internally and get back to you within the week.

Issue was on our side. We were using the ad unit name instead of its ID when initializing the MAInterstitialAd.

My suggestion is that this should be a clearer error in the logs (at the moment it just says "Please check ID for INTER"), mentioned in the debugger or the quality tool, since it's not straightforward to pinpoint.
