Inconsistency between ios and Android

[miraclemaker]

If I open up the demo snack in Expo Go on both Android and iOS, and look at the 'default header' example. On Android when I start scrolling the header collapses when I hit the bottom of item 1. On iOS it doesn't disappear until the bottom of item 4 - much further down the page.

Can we make this consistent? Ideally I would like to be able to control this offset because I would like my header to collapse as soon as you start scrolling.

Many thanks.
