Deeplinking using Universal links in iOS14

Our application is a WebView application which is hosted on an on-premise server. This server does have the AASA file hosted on it in the correct format.

We also have hosted a server on the public internet with the same domain name with a static webpage, to host the AASA file, so that it gets linked with the app when the app is installed the first time from the Appstore/TestFlight.

This setup was working with iOS 12 to all the way to iOS 13.7

However, since the iOS 14 update the Universal Links seem to not work anymore.

I've followed the Apple Documentation here [https://developer.apple.com/documentation/safariservices/supporting_associated_domains?language=objc), but adding that ?mode=developer in the associated domain section that does not seem to help either.
Turns out you need to enable "Associated Domains Development" in the Developer settings in iOS. (Settings app -> Developer -> Enable "Associated Domains Development" in the "Networking" section) - Hope this helps!
how can this be seen in ios simulator?
