Scroll to EditText in NestedScrollView is not working

Question

I have long scroll form, and I need to scroll to its position on form is not valid input (for example, scroll to email edit text when it's not valid email or empty field)

I am facing 2 issues with scroll to EditText inside NestedScrollView

1. When one edit text is focused, all times scroll to take me directly to the focused scroll view, not to provided view coordinate
2. When there is no focused item, it's scrolling in a bad way, the wanted Edittext showing trimmed from the button

Note: I am using NestedScrollView with CoordinateLayout Below is the layout

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
