Did you test this on previous iOS 16 betas? If so, did it work there? That is, is this a 16.0b4 regression?
We discovered the problem with beta 3 and it's still there in beta 4 (we haven't tested the previous betas)
What API are you using to issue that request? NSURLSession? A web view of some form?
It's not a webview but a standard API from Apache Cordova native platform version 5.0.1
