Vertical FlashList with nested horizontal ScrollView scrolling issue on Android

[lucasroges]

Hi, everyone.

I have a situation with a horizontal ScrollView inside a vertical FlashList. Sometimes, on Android devices, when I try to scroll horizontally, the screen ends up scrolling vertically. Each list item occupies most of the screen and I debugged that the touches causing this behavior have a dx > dy, so the ScrollView should handle them, as far as I am concerned.

Did anyone ever spotted a similar behavior?

So far, I tried manipulating the FlashList's scrollEnabled property using onTouch* handlers and using event.stopPropagation() inside the ScrollView's onTouch* handlers, but none of these actually worked to solve the problem.
