AdMob Ad not showing up after publish

you found any the solution to this ?

I wrote mistakly „Google Play Store“ But I mean App store. I wrote to Google dev Team and they said that sometimes it takes 18 days or 4 weeks Till real ads will be shown 🥲

Would this be the reason I am getting "‎Error Code 3 : ERROR_CODE_NO_FILL" ??
I have had the ad units installed since i started working on the app a few months ago.
Android works fine, but iOS ads do not work. I seems the requests all go through, but they are not being filled or show on iOS.

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

Hi,

I found the following answer, and it is working.

"It seems that this is recently a very common issue as AdMob has been going through changes. Myself and it seems many others on the AdMob forum, have been able to successfully link the app from the App Store to AdMob just by reaching out. See link below to the forum and just post a new conversation with your issue including App Store link, and someone should be able to help within 24 hours it seems. Good luck!"

It can take up to two working days till the ads are displayed. Also ensure that you have entered the link to your App Store Entry of the app in Admob App Settings
