Reset nested Stack.Navigator to initial screen.

[samsnori]

How can I reset a nested stack to its initial route when navigating back to its parent navigator?

When I've got a stack like this:

Home
Intro
User
   Form1
   Form2
   Form3

I navigate from User -> Form1 -> Form2 -> Form3 -> Home.Then when I want to navigate to the Form1 screen again I see the Form3 first for a short time (only on iOS), then Form1 is opened. I want to be able to directly show Form1. I need a way to reset the nested stack when I navigate from Form3 to Home.

If I'm correct the way to do this, is using the reset action. Which has a big "warning" message there so I hope to avoid that approach if possible. This solution seems to work, however it also unmounts/mounts my component which I would like to prevent.

Is there a way to reset a nested stack navigator back to its initial route when I go back from the nested navigator to the parent one? (e.g. from Form3 to Home/Intro/User)?
