Answer 1

Add the following meta-data inside the tag in your android/app/src/main/AndroidManifest.xml file:

<meta-data 
   android:name="com.google.android.gms.ads.APPLICATION_ID"
   android:value="ca-app-pub-[your id]" />

if you are using Android 12 or 13, add the following line after the tag if already added ignore it

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

uninstall and install your app

check if your id is active or not in admob

turn off any adbloker or adbloking dns
