How to GetUserId() in a Web Reactive app of a logged in user in Web Tradicional app?

I have an app built on Web Reactive that calls the Built-in function GetUserId (). The user logs in successfully, with redirects to an app built on Traditional Web, which ultimately redirects to the Web Reactive app. For Traditional Web apps the user is logged in, but not for Web Reactive apps.
