iOS App crashes for Applovin ads

[iOS Developer]

Hi,

I have used the Google Mobile Ads SDK to load and display ads from AppLovin in my iOS App, To integrate i have followed guide:

https://developers.google.com/admob/ios/mediation/applovin

so far it was showing App lovin ads, but since yesterday morning the App is crashing whenever an interstitial Ad request is made and AppLovin ad is received.

The error log:
AppLovinAdapter: AppLovin adapter collecting signals.

AppLovinAdapter: AppLovin adapter version: 13.0.1.0

AppLovinAdapter: AppLovin SDK version: 13.0.1

[AppLovinSdk] DEBUG [ALSdk] Setting plugin version: 13.0.1.0

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unknown ad size: '

[AppLovinSdk] DEBUG [ALHealthEventsReporter] crash reported with code 200 and extra parameters {
    "top_main_method" = "NSInvalidArgumentException Unknown ad size: ";
}

I am loading an Interstitial Ad, there is no option to set Ad size, but app crashes with error - Unknown ad size.

I have updated to latest sdks too.

Additional Info:
GoogleMobileAds SDK - 11.11.0

Please help!

Thanks,

[Luis Gualandi]

That started happening with me yesterday also when loading interstitial ads. Just a couple days ago I was testing applovin ads on the same device and it didnt happen

Thank you for contacting the Mobile Ads SDK support team.

It’s always advisable to use the latest version to prevent conflicts, so ensure you’ve integrated the most recent version

I successfully integrated appLovin  version 13.0.1.0 into our Google sample application and tested. It performed as expected. Could you provide your sample project where the issue occurs?

Additional info: It might be happening on test mode devices only. I made a test and was able to load an Applovin interstitial ad with test mode off, switched the device back to test mode on Admob console and it started throwing the error again. With test mode the error occurs by either setting single ad source on the inspector or by waiting for applovin to be selected in bidding

Hi,

As stated in earlier mail, kindly provide us your sample project where the issue can be observed. Once received your sample project we would be checking your implementation and share it with wider team for further assistance.

Hi,

Last night, we paused the device for Test Ads, and after that, I didn't encounter any crashes. Everything seems to be working fine now.

It looks like the issue started after adding my device as a Test Device on the dashboard.

Thanks for your help anyway!

Yes, this is happening on test mode only and also it seems to be on Applovin's side. I opened an issue on their github and they said they're looking into it but yet no resolution
