What to do if page content automatically updates?
If there is content that automatically updates on a webpage, users must have the ability to pause, stop, hide or to control the frequency of the updates, unless the content is **essential** (per WCAG "if removed, would fundamentally change the information or functionality of the content, and information and functionality cannot be achieved in another way that would conform").
