- Success Criterion 2.2.1
- Conformance level A
Session Extension Allowed Fewer Than the Required 10 Times
2.2.1 — Timing Adjustable
Scenario
Setting
A video streaming service's show detail page
What’s wrong
Extension allowed fewer than 10 times when the extend route is relied on.
Example
This shows up on a video streaming service's show detail page: extension allowed fewer than 10 times when the extend route is relied on.
Why it matters
People who read, type, or move slowly, including many screen-reader users. On a video streaming service's show detail page, this barrier means they lose their place when content moves unexpectedly.
How to test
Repeatedly extend the session when warned: it must allow at least 10 extensions — fewer fails.
How to fix
The time limit must be removable or adjustable (to at least 10x) before it starts, or extendable via a warning giving at least 20 seconds to respond with a simple action.
Outcome
Corrected, a video streaming service's show detail page now lets a visitor read the content without losing their place.
Who is affected
People who read, type, or move slowly, including many screen-reader users.
