You can also simply call requestLayout method after changing Group visibility to View.INVISIBLE.

fun makeGroupInvisible(group: Group) {
    group.visibility = View.INVISIBLE
    group.requestLayout()
}

Problem is that android.support.constraint.Group updates visibility of its members in updatePreLayout method which is called from onMeasure in ConstraintLayout.
