Outdated Android Supported Library

[dilawer]

Description:
I have followed the instructions carefully and exactly the same way mentioned at the link. However at the dashboard of onesignal, I see against my testing device it is shown "Outdated Android Supported Library". What else am I missing? Any help would be highly appreciated.

Environment
My gradle version:
6.1.1
My project level build.gradle:
buildscript {
repositories {
maven { url 'https://plugins.gradle.org/m2/' } // Gradle Plugin Portal
}
dependencies {
classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.12.6, 0.99.99]'
}
}
My app level build.gradle:
buildscript {
ext {
buildToolsVersion = "29.0.2"
minSdkVersion = 16
compileSdkVersion = 28
targetSdkVersion = 28

}

}
My react-native version in package.json
"react-native": "0.61.2",
My AndroidManifest.xml

...
android:launchMode="singleTask"
...

To give you some more technical details, the targetSdkVersion and the Android Support library version of the app must match.
