WCAG 2.2.2 and repetition over time.

Hi all,

I'm working with an app that uses a blinking dot to indicate a new notification. The blinking is intended to draw attention, and it lasts for 4 seconds, then stops. After a pause of 30 seconds, it blinks again for another 4 seconds — and this cycle repeats.

My questions are:
Would such a pattern (blinking <5s, repeating every 30s) be considered compliant with WCAG 2.2.2? What if the pause was longer?
If it's technically compliant, could it still be considered a bad practice from an accessibility perspective?
Are there any known best practices or real-world examples for handling this kind of intermittent attention-drawing animation?




Kind regards,

Kia
