try this:

MobileAds.initialize(this, getString(R.string.admob_app_id));

I had this issue as well today. My app was not suspended, but the apk name change did work. We had renamed a test app to release it to production; we changed the apk name as a result. This screwed up our ad fill on both MoPub and Admob.

Answer 4

In my case this was the error as result of requesting a geo-restricted ad from a region that's not supported for that ad. If I hardcoded the location for the ad request bundle to be inside the acceptable region, or not include a location in the request at all, the ad was rendered just fine; otherwise I had the same error as OP in console.

Answer 5

It might be because you're not waiting for the ad to load.

For me implementing the AdLoaded method of the AdListener did the job.

    mAdInterstitial.loadAd(AdRequest.Builder().addTestDevice("XXXXXXX").build())
    mAdInterstitial.adListener = object : AdListener() {
        override fun onAdLoaded() {
            mAdInterstitial.show()
        }
    }
