Hello @Galogarsa_Channel_Ga  
Could you please check that you are using the correct app IDs in the AdMob section of your Project Settings?  
Also please check that each AdMob component (banner, interstitial, and reward) have valid Ad Unit IDs.

The App IDs on project settings need to have this format: ca-app-pub-123456789123~8071331014

and the Ad Unit IDs need to have this format: ca-app-pub-123456789123/5169354241

You can find more information about the IDs in the following link: [https://support.google.com/admob/answer/7356431?hl=en](https://support.google.com/admob/answer/7356431?hl=en)

Hi @Galogarsa_Channel_Ga Thank you for sharing more information!  
Have you downloaded the apk?  
Could you please check your App’s status on AdMob?

It needs to be “Ready” in order to see real ads.

More information about AdMob Status can be found here: [About app readiness - Google AdMob Help](https://support.google.com/admob/answer/10564477?hl=en)
