@ronnyhartenstein This is excellent. Clean, straightforward and flexible. I'm wondering why it isnt more widely accepted as a suitable solution? Have you found any shortcomings i.e. deep linking, navigating based on push notification payloads (after verifying they are logged in), etc? Thanks again!

how would you logout from the MainNavigator and redirect to the Login screen found in the OnboardingNavigator using redux?

Sometimes I am getting weird errors when transitioning between screens this way. Had to add setTimeout which is beyond hackish
