Hi Lars,

nowadays screenreaders synchronize DOM and their buffer continuously. Approximately 10 years ago there were problems and screenreaders didn't always catch dynamic updates to page content - that was known as the latency issue. I haven't noticed that problem in many years, now.

Live-Regions are not  connected to that issue.

If you have added content dynamically, you will need to navigate to the new content with a screenreader to check, whether the content is there. It should be.
