Enable verbose logging with the following code:
AppLovinMAX.setVerboseLoggingEnabled(true);
<application>
⋮
<meta-data android:name="applovin.sdk.verbose_logging" android:value="true" />
⋮
</application>

UAppLovinMAX::SetVerboseLoggingEnabled(true);
MaxSdk.SetVerboseLogging(true);
AppLovinMAX.setVerboseLogging(true);
AppLovinMAX.set_verbose_logging(true);
AppLovinSdk.getInstance( context ).getSettings().setVerboseLogging( true );
AppLovinMAX.setVerboseLogging(true);
AppLovinSdk.getInstance( context ).settings.setVerboseLogging( true )
applovin.set_verbose_logging_enabled(true)
[ALSdk shared].settings.verboseLoggingEnabled = YES;
ALSdk.shared().settings.isVerboseLoggingEnabled = true
To verify that you enabled verbose logs, check for the line Verbose Logging On: true in the AppLovin SDK initialization block:
========================================
AppLovin SDK
Version: 12.13.14
⋮
Verbose Logging On: true
⋮
========================================
You can then find AppLovin verbose logs in logcat or Xcode terminal as lines that start with /AppLovinSdk: [AppLovinSdk].
