This is related to Universal link. referrerURL parameter is available only in iOS 11/12. I wanted to take user back to the referal URL in some use cases. Is there any workaround for iOS9/10 to get the referal URL? If no, can we open Safari app programatically without passing the URL.
There is no workaround.
