IPointerDownHandler and ISelectHandler lagg response on IOS

Hey everyone

We are currently in the development of a game that we are gonna release on all consoles and platforms but today we noticed a bug that we are not sure how we should solve it.

I'm having a button where i write my own ISelectHandler behavior.
It all works fine for PC, Android, PS4, Xbox, Switch ,... But on our IOS (Iphone) test device we have a lag issue.

The ISelectHandler triggers a few seconds after the finger enters it. The same for IPointerDownHandler.

We are not sure if this is a known bug or if there is something we can do about this ?

Have a great day
Niels
