title: "Unhandled Promise Rejection: NotAllowedError: The request is not allowed by the user agent or the platform in the current context .." with PWA on iOS
body: <p>I am currently facing an issue while implementing Web Share API (Level 2) in Vue 3 using it to share/download images on iOS 14 (as experimental feature) and iOS 15 in a Progressive Web App context.</p>
  <p>Observation: When the application is running directly in the Browser (not in the PWA Context - which is a local PWA accesible through the homescreen Bookmark on iOS), it also works as expected without any errors.</p>
  <p>Installed as a PWA, however, sharing works as expected THE FIRST time, but AFTER saving the image, it refuses to trigger the native sharing mecanism with the error message (note it ALWAYS works once):</p>
  <blockquote>
  <p>Unhandled Promise Rejection: NotAllowedError: The request is not
  allowed by the user agent or the platform in the current context,
  possibly because the user denied permission.</p>
  </blockquote>
  <p>The navigator.share is triggered directly by a click event, the resource is also loaded in advance and sharing.</p>
  <p>It seems to work fine on Android Devices as expected but on IOS</p>
