Pasting not detected as Text Changed on iOS

Hi, hoping someone has come across this as I can’t find a dedicated post…

I have a problem where I need a user to be able to paste in a phone number and a series of cases to fire when the text change is detected.

It’s working fine when I manually type the number and pasting works on desktop. But when I paste on iOS, it’s not being picked up as a text change. I’ve also tried using onKeyUp with no luck. Am I missing something about why the behaviour is so different?

A simplified version of this is here: https://2azts1.axshare.com/#id=0ey9x6&p=page_1. Sample file below.

Any help much appreciated!
