Obtaining Adverstising ID's

Apps updating their target API level to 31 (Android 12) or higher will need to declare a Google Play services normal permission in the AndroidManifest.xml file.

Navigate to the android/app/src/main directory inside your project's root, locate the AndroidManifest.xml file and add the following line just before the <application>.

<uses-permission android:name="com.google.android.gms.permission.AD_ID" />
