As a friendly recommendation, instead of sending anonymous users straight to SSO as soon as the app loads, it’s better to first show a short landing page. This page can simply include a “Continue to login” button, and the SSO redirect starts only after the user clicks it. This gives the browser a moment to recognize the app as installable and ensures there is a clear user interaction. After login, the user is taken to the normal home page, while the landing page is only shown to anonymous users.
