I am facing a weired situation where i have implemented a googleadmob in react native app.
<AdMobBanner
bannerSize="fullBanner"
adUnitID="ca-app-pub-3940256099942544/6300978111"
testDeviceID="EMULATOR"
didFailToReceiveAdWithError={this.bannerError} />
where ca-app-pub-3940256099942544/6300978111 is the test id provided by googleadmob
but when i created new Adunit ID and replaced test id with the newly created ad unit id i am unable to any ads Why ?? Note : i am working on dev environment i guess it won't affect but still ..
