UnityMediationAdapter (v4.12.1.0) failed to initialize with proguard minify enabled

[caro...@gmail.com]

Here are the message on init complete:

Key = com.google.android.gms.ads.MobileAds, State = READY, Desc = , Latency = 918
Key = com.google.ads.mediation.applovin.AppLovinMediationAdapter, State = READY, Desc = , Latency = 2090
Key = com.google.ads.mediation.unity.UnityMediationAdapter, State = NOT_READY, Desc = Failed to initialize adapter. com.google.ads.mediation.unity.UnityMediationAdapter does not implement the initialize() method., Latency = 58

I'm using Android Studio Jellyfish 2023.3.1 Patch 2, AGP 8.4.2, Gradle 8.6,

with proguard rules:

-keep public class com.google.android.gms.** { public *; }
-keep public class com.google.ads.** { public *; }
-keepattributes *Annotation*
-dontobfuscate

Ads-related dependencies are:

implementation 'com.google.android.gms:play-services-ads:23.2.0'

implementation 'com.google.ads.mediation:applovin:12.6.0.0'

implementation 'com.unity3d.ads:unity-ads:4.12.1'
implementation 'com.google.ads.mediation:unity:4.12.1.0'

I also use Firebase in the project:

classpath 'com.google.gms:google-services:4.4.2'
classpath 'com.google.firebase:firebase-crashlytics-gradle:3.0.2'

implementation platform('com.google.firebase:firebase-bom:33.1.2')
implementation 'com.google.firebase:firebase-analytics'
implementation 'com.google.firebase:firebase-crashlytics'

As can be seen in the log message I pasted, applovin adapter works as intended. Also if I disabled proguard minify, the adapters all initialize correctly. Please help me pinpoint the issue. Thanks!
