Rewarded "Dummy" Ad Bug

Bug report

Describe the bug Dummy Rewarded ads do not load when using test ID’s. Instead, it gives out an error as I pasted below. However, when using my actual ad ID it works (hope I don’t get flagged 🙏!).

Steps to reproduce

Steps to reproduce the behavior:

1. Run the AdMob example as seen on the pub.dev example page
2. Watch the error populate on the screen

Expected behavior

The ad successfully loads and populates the widget tree

This DummyAdapter error occurs when “Personalized Ads” is disabled or “limit ad tracking” is enabled on iOS, which means IDFA cannot be used.

Check your test device, then rewarded ads will work normally. For iOS14, Settings -> Privacy -> Apple Advertising -> Personalized Ads, check if it’s turned on. For iOS13 and earlier, Settings -> Privacy -> Advertising -> Limit Ad Tracking, check if it’s turned off.

Find more info here. https://groups.google.com/g/google-admob-ads-sdk/c/IJHU0Qqj1C0/m/x0Txr8MPBwAJ

I had the same problem, Cannot find an ad network adapter with the name error. In my case, not rewarded ads but banner ads. (google_mobile_ads version: “0.13.4”)

And I fixed this error by putting my app-ads.txt the line. google.com, pub-3940256099942544, DIRECT, f08c47fec0942fa0

If you use app-ads.txt, please check the details in the official docs, and try it. https://developers.google.com/admob/android/test-ads
