@DTS Engineer In General, Universal link is working for notification and deep linking ..We debug also and looks fine for us in the upper environment and looks like issue in lower environment Our App still not working for upper environment where universal link configurations are correct .. Our app receives a login redirect call from the backend, but AsWebAuthenticationSession + Universal Link has weird behaviour but at the same time AsWebAuthenticationSession + customURL works perfectly. As per apple document it can be https or customURL also. https://developer.apple.com/documentation/authenticationservices/authenticating-a-user-through-a-web-service

ASWebAuth + Universal link issue -In login iOS application we are launching the Login URL in the ASWebAuth to support the auto-saving of the username and password. -It enables the passkey options seamlessly. When user enters into the Native app using the passkey or saved credentials, we send an Auth-Return URL to Login system -login in response of successful authentication redirect user to the Auth-Return URL along with an authenticated Auth-Code value. -When the Auth-Return URL is evaluated, it is expected that we should redirect user back the Native application and proceed with the session of the user along with the Auth-Code received. Problem is ASWebAuth not dismissing and handover to app
