Google Ads won't display

I've had ads in my Xamarin app for years. Recently I've started getting this error.
Missing google_app_id. Firebase Analytics disabled. See
(11728): Ad failed to load : 3
I can load google's test ad. Nothing in my code has changed. Any ideas?

    AdMob does not always have an ad to return for every request. This may happen particularly if you have just registered your AdMob publisher ID, as it takes some time and multiple requests before the new ID starts returning ads.

    As mentioned we've had an Ad ID that works for years. Its not from lack of ads. The same Ad ID will load ads in our IOS app. The problem seems to be that google has changed something when it added the "firebase" module to its ad services. I'm not sure how they intend for us to reconfigure things. I've added a google-services.json to my project. Do I need to put my ad ID into that file?

    Try to compile app signing it for distribution. In past, for Admob, app sign wasn't mandatory for showing banners but actually it seems to be.
