@shefich

Can you submit a minimal sample and complete log-trace to the support team. The sample/log will be needed to prove that this issue is from Admob and not AppLovin. Right now I do not see any Admob in the stack trace.

Thanks, Nick

@NVentimiglia can't share minimal repro as I deleted this library as it has errors. I don't have AppLovin SDK in my project, only Mediation plugin for Admob. Based on my logs the crash happen after app goes backround while showing interstitial (firebase_screen_class: AppLovinFullscreenThemedActivity). But here are steps:

• download unity 2021.3.34
• add Google Mobile Ads Unity Plugin v8.7.0
• add AppLovin Unity Mediation Plugin 6.9.1
• write code to load interstitial ad
• build on device and try to show interstitial
• crash happen

Here are stacktraces for this type of error: stacktrace_appl.txt

Thanks I will take a look.
