You will see 2 IDs starting with "ca-app-pub-.xxxxxxxxxxxx"

one is ADMOB_APP_ID -> use this while installing plugin

another is YOUR_AD_ID -> this is correct for ads (above will give NETWORK ERROR for ads), now have "internal error", gave my address details also, will wait and try again after some time.

I have used cordova, react, admob - so some may be unnecessary for you
