I just published a wkwebview app. But the app is only compatible with ios 15.0 and above. Please tell me, how can I update my app to make it compatible with older ios versions?

WWDC22 "What's new in WKWebView"  https://developer.apple.com/videos/play/wwdc2022/10049/?time=470 inspect and debug it yourself in third-party browsers on iOS, When I say third-party browsers, I mean on iOS16, you can use third-party browsers ，like use chrome browsers to debug my website？ thinks！

Only one particular URL does not load in the webview. Every other URL works. Not able to trace the issue but the console logs indicate the following error. Can anyone help around with this please? Provisional navigation does not even start.
