Question

You guys have any idea as to what may be the possible cause of this error in UMP SDK for Android?

Publisher misconfiguration: Failed to read publisher's account configuration; please check your configured app ID. Received app ID: ca-app-pub-3940256099942544~3347511713.

ca-app-pub-3940256099942544~3347511713 is Test Application ID

and this Error Pops up when trying to use Obtaining Consent with the User Messaging Platform

I followed the procedure as outlined in https://developers.google.com/interactive-media-ads/ump/android/quick-start

I do not get an option to create / view Funding Choices account, but still this is a test application id.

public void onConsentInfoUpdateFailure(FormError formError)
{
}

Answer 1

I fixed this error by logging into Admob and configuring my GDPR and IDFA messages here: https://apps.admob.com/v2/privacymessaging

After I configured and allowed those messages the error went away, and it worked even while displaying test ads on an emulator.
