Interstitial ad is not displayed in WKWebView

Hi, I am with Xcode Version 14.2 (14C18) and iOS Deployment Target 16.2 I'm developing a simple app and have no issues with AdMob interstitial ads anywhere. The only problem I have is when I have WKWebView loaded. In the console, I can see that the ad loads and then runs but with no visible result. I tried to hide the WebView when the ad started, but to no avail - a white page. Any guidance to resolve the issue would be helpful. Thank you in advance!
