title: The ad does not appear in the published app
body: <p>A few days ago, my app was published on the app store. At the development stage, I added an advertisement in the form of a regular banner. With the test identifier, the test ad was displayed successfully. But with a real identifier, the app was showing a blank banner. I read that in iOS apps with real identifiers , Ads are not shown until publication in App Store. But even a few days after the publication, the advertisement is still not shown.
