I've seen this appear in a number of support tickets, but nothing seems to correspond to my use case. For additional testing, I used an app id and ad unit ID from another app in our organisation; the ads using those credentials appear just fine, so implementation doesn't seem to be the problem.
Could you point me in the right direction? The error message in the console is quite vague, and AdMob dashboard doesn't seem to indicate a problem with anything so I'm not sure where to go from there.
