Observed behavior and steps to reproduce
On iOS, try to drag one PointAnnotation, if you press and try to drag all the map start to scrolling and the PointAnnotation will not move. To make PointAnnotation moving you need to LongPress on it (at least 1 second), than if you drag it, it start moving.
Secondly, all PointAnnotations appear to be at a level below the LineLayer, they should be on top level as happens on Android.
Expected behavior
Expected behavior is the same that works running this code on Android. When you try to drag one PointAnnotation it starts moving immediately after pressing it and dragging, you don't need to long press on it.
Secondly, here on Android, all PointAnnotations appear to be at the top level, over the LineLayer.
Notes / preliminary analysis
Note that this code works as expected on Android but not on iOS.

Video that show how it works correctly on Android: drag start immediately after press and PointAnnotation above LineLayer. https://github.com/rnmapbox/maps/assets/107206974/dbb9a22e-75db-458b-83fa-d4c5e0f7532a
On iOS you need to longpress before you can start dragging and PointAnnotation are below LineLayer
