  <Accordion id="q1" title="What is the coverage scope of Global Visible Watermark?">

    * Live Streaming
    * Video Conferencing

  <Accordion id="q2" title="If the administrator turns off Global Visible Watermark, will the previously configured Contacts watermark also be disabled?">
    **A:**

    * When Global Visible Watermark is **on**: It overrides any individually configured watermarks in other applications, following the global watermark settings.
    * When Global Visible Watermark is **off**: Any watermarks that were individually configured in other applications will remain active (turning off Global Visible Watermark does not affect them).
  </Accordion>

  <Accordion id="q3" title="Do exported documents, images, and other files have watermarks?">
    **A:** No. Global Visible Watermark is an in-app foreground watermark, not a content watermark.
