Re: JAWS/IE 11 not announcing aria-live regions?

You're welcome.
The only thing aria-atomic does is to have screen reader announce the
entire content of the div when an update happens.
When you update the content of the time span in the following, the
screen reader will only announce that value, e.g. :3:31pm).
<div aria-live="polite" aria-atomic="false">The time is <span
id="time">3:30pm</div>
If aria-atomic is set to true and you make the same update the screen
reader will announce" the time is 3:31pm".
