Re: Looking for aria-live examples that actually work as expected on Desktop Safari (or Chrome) with VoiceOver

Thanks, Birkir.

I've tried the Live region playground, but again: Safari (Version 10.1.1 (12603.2.4)) doesn't announce any new or updated information. I'm using default VoiceOver settings. Can you conform that this works on your end? :)

I also followed your advice and changed my own example so this hidden on load (in the CSS):

`<div id="confirmation" role="region" aria-live="assertive">Thanks for subscribing</div>`

And its display property is set to 'block' when a button is activated, like so:

`document.querySelector('#confirmation').style.display = 'block';`

Unfortunately, this makes no difference. VoiceOver is quiet as a mouse :(
