In the code base I see
void UKismetSystemLibrary::EXPERIMENTAL_ShowAdBanner(bool bShowOnBottomOfScreen)
{
if (IAdvertisingProvider* Provider = FAdvertising::Get().GetDefaultProvider())
{
Provider->ShowAdBanner(bShowOnBottomOfScreen);
}
}
for the Kismet nodes you are using
Sounds like it should be finding Admob automatically and it is not
I suggest putting on Answerhub, stating what your is with Admob
