Ad unit doesn't match format in AppOpenExample

[mobile-ads-github]

Hi!
I'm trying check the AppOpenAd format, but in public samples (AppOpenExample) (both java & kotlin) every load of the ad fails with an error:

{
  "Code": 3,
  "Message": "Ad unit doesn't match format. <https:\/\/support.google.com\/admob\/answer\/9905175#4>",
  "Domain": "com.google.android.gms.ads",
  "Cause": "null",
  "Response Info": {
    "Response ID": "null",
    "Mediation Adapter Class Name": "",
    "Adapter Responses": [],
    "Response Extras": {}
  }
}

Ad Unit ID wasn't changed, I'm loading the original ca-app-pub-3940256099942544/3419835294

Thanks for reporting this, I will submit a fix asap. On your end change the ad unit id to:

ca-app-pub-3940256099942544/9257395921

I'm getting the same error in an iOS example:

App open ad is not ready yet.
Start loading app open ad.
App open ad failed to load with error: Ad unit doesn't match format. <https://support.google.com/admob/answer/9905175#4>

Should I create a new issue there?
