Dynamic Updates or alerts are not announced to screen reader users, or they are announced incorrectly.

Ensure that screen readers announce when alerts or new page content displays, whether a completely new page or dynamic content within a page or frame.

Use <aria-live> regions to ensure that dynamic content is announced to assistive technology, then move the screen reader focus to the first new element added to the page.

• Consider ARIA alert level (polite, assertive), and whether all page content or just the page content that changes needs to be announced (atomic level).
