[SOLVED] (Android) Error: Admob not found + not loading ads

I followed the simple Android appodeal installation guide on https://github.com/appodeal/react-native-appodeal. Double checked the manual installation section, all of that has been done. When I run the app on Android all builds fine but on the first load, I get a small notice at the bottom stating: "Error: Admob not found". I have the onRewardedVideoLoaded and onRewardedVideoFailedToLoad listeners set up that works fine on iOS, however, none of them return anything on Android, so the ads just simply never load.

Here's my /build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

ext {
buildToolsVersion = "28.0.3"
minSdkVersion = 16
compileSdkVersion = 28

}

    afterEvaluate{
        if((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
        android {
            compileSdkVersion rootProject.ext.compileSdkVersion
            buildToolsVersion rootProject.ext.buildToolsVersion
        }
    }
}
}

    // quickly to Android tooling updates
    classpath 'io.fabric.tools:gradle:1.+'
}
}

allprojects {

    mavenLocal()
    google()

    maven {
