### Why is this important?
Some individuals might need more time to read or interact with a page than the author expects.
If the page auto-refreshes while they are still reading or working, it might prevent access to content by resetting their location on the page.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* Remove the `<META>` tag that causes an automatic page refresh (e.g., `<META HTTP-EQUIV="Refresh" CONTENT="10">`) and use a different method to update information on the page
* **Or**, provide an option to turn off, extend, or adjust the timing of the page refresh
* **Or**, at the top of the page, provide a single line of explanation and link to a non-refreshing page. For example, "This page automatically reloads every 10 seconds. A `<a href="..."> non-updating equivalent page </a>` with a refresh button is available."
