AdMob Ads Stuck on 'Ad Loading...' in iOS Release Build (TestFlight/App Store)

Integrations

I'm facing an issue with AdMob ads in my iOS app. The ads work perfectly in debug mode(with test ads), and test ads are displayed without any problems. However, when I create a release build for TestFlight or submit it to the App Store, the ads fail to load and get stuck on the message "Ad Loading...".

Also, the Android App is working fine and is published in the Play Store.

What have you tried so far?

I downloaded the code and verified that the AdMob app ID is correctly set in Info.plist.
Ensured proper initialization of the AdMob.
Checked network permissions (e.g., NSAppTransportSecurity settings) in Info.plist.

Did you check FlutterFlow's Documentation for this topic?

Yes
