Hello if your app shows the adds with test ids, it means all is working fine. You can implement the GADBannerView delegate, to know the specific error. I had the same error, the error that I have retrieve was “no ads to show” My app is now success showing ads in AppStore, I have not maked any change, just waited 4 weeks, and ads has started to show. My recommendation is try to always test only with the test ids, when I test with the real ids the ads stop showing, is like a shadow ban. Yesterday I updated my app, and now ads not showing 😅, I think after every update, ads stops to work some days, I’ll update future comments
