title: Updating Old url to new url in PWA
body: <p>I am trying to change the start_url of my PWA app from one page to another but need to understand the working. Can anyone please tell me what will happen to users of my PWA app user(with old start_url). Is there any some kind of update happen after which old user can get the updated start_url.</p>
