Hello AdMob Team and Community,

I am experiencing a persistent [googleMobileAds/no-fill] error for my iOS application and would appreciate any guidance.

Despite receiving an official email a few hours ago confirming that my app has been reviewed, approved, and that all ad serving limits have been removed, I am still unable to receive any ads, including on TestFlight builds.

App & SDK Details:

AdMob App ID: ca-app-pub-3600196907552487~9882479398
Ad Unit ID (Rewarded): ca-app-pub-3600196907552487/3924695268
Bundle ID: com.talhaustundag.SnipSwipe
Framework: React Native
SDK: react-native-google-mobile-ads (Version: 15.4.0)
Platform: iOS (Testing on iOS 17+)

The Problem: Every ad request fails with the same error: [Error: [googleMobileAds/no-fill] Request Error: No ad to show.]

This happens consistently in the following environments:

On a physical device during local development.
In builds distributed via TestFlight.

What I Have Already Done (Troubleshooting Steps):

Received App Approval: I received an email on July 8, 2025, around 1:00 PM (GMT+3) stating that my app was reviewed and approved, and that ad serving restrictions were lifted. I have waited several hours for this to propagate.
Verified AdMob Account: My payment information is complete and my account is fully verified.
Checked AdMob UI Settings:
- Blocking Controls: I have minimal to no blocking controls enabled.
- eCPM Floors: I have not configured any eCPM floors.
Tested on TestFlight: The no-fill error persists in the production-like TestFlight environment.
Created a New Ad Unit: I created a brand new rewarded ad unit, but the result was the same.
Verified Project Configuration:
- The Bundle ID matches exactly across my Xcode project, App Store Connect, and the AdMob UI.
- The GADApplicationIdentifier is correctly set in my Info.plist.
- My app-ads.txt file is correctly implemented, accessible, and has been crawled by Google.
- The SKAdNetworkItems list is up-to-date according to the latest Google documentation.

My Question:

Given that my app is now officially approved and all serving restrictions are supposedly lifted, could there be a lingering issue on the backend or a longer-than-usual propagation delay? Despite the approval, it seems my account is still unable to get any ad inventory.

Is there anything else I can check or any information I can provide to help diagnose this issue?

Thank you for your time and any assistance you can provide.

Bes regards,

Talha
