WKwebview disable "Prevent cross site tracking" for Mac app

How to disable "Prevent cross site tracking" in WKwebview for Mac app. "NSCrossWebsiteTrackingUsageDescription" key in info.plist doesn't seem to work. Also, no cookies received in decidePolicyForNavigationResponse delegate method of WKwebview. Though can see in network traces. Does WKwebview blocks 3rd party cookies.

Only on macOS catalina, NSURLSession fail with NSURLErrorClientCertificateRequired

The ssl certificates are proper according to new requirements for catalina. Can see a response 403 from server in console by enabling CFNETWORK DIAGNOSTICS but it is failing with NSURLErrorClientCertificateRequired. The certificates are also being shared properly confirmed from wireshark & CFNETWORK DIAGNOSTICS. Authentication works properly on safari and chrome, without any errorOne observation: There are multiple api calls throughout the session. When tried these call explicitly on chrome twice or thrice, the authentication worked proplerly on app too. How does authentication on chrome/safari affect an app? Is it something to with security settings on catalina. After this there are not authentication errors at all on my system. The issue is only observed on macOS Catalina.
