Android Question Firebase Admob ERROR CODE 0

[Addo]

i have followed this tutorial

https://www.b4x.com/android/forum/t...b-ads-integrated-with-firebase-backend.67710/

but after the initialization i got error code 0 and no ads shows what could be the problem ?

here is the code

Private IAd As InterstitialAd

IAd.Initialize("iad", "ca-app-pub-1926540584968182/9190797497")
IAd.LoadAd



Sub iad_ReceiveAd
    Log("Received")
End Sub

Sub iad_FailedToReceiveAd (ErrorCode As String)
    Log("not Received - " &"Error Code: "&ErrorCode)
    IAd.LoadAd
End Sub



Sub iad_AdClosed
    IAd.LoadAd 'prepare a new ad
End Sub

what could be my mistake ?

You can see the error codes here: https://developers.google.com/android/reference/com/google/android/gms/ads/AdRequest

Start with the test ids: https://developers.google.com/admob/android/test-ads#sample_ad_units

test ads works very well maybe this is something with a verification of my ad unit i will check after 48 hours
