Can not navigate while app is in background

Question

I use Navigation Component to navigate between fragments.

Init navigation in main activity:

val navHostFragment = NavHostFragment.create(R.navigation.nav_graph)
supportFragmentManager
        .beginTransaction()
        .replace(R.id.container, navHostFragment)
        .commit()

Navigation to another fragment in splash fragment:

findNavController().navigate(SplashFragmentDirections.actionSplashFragmentToHomeActivity())

In splash i do auth, it takes some time, after auth i navigate to home fragment. If i minimize app (press home button) in splash fragment then navigate() doesn't work and when i open app again it remains in splash fragment

In console:

NavController: Ignoring popBackStack to destination my.app/homeFragment as it was not found on the current back stack
FragmentNavigator: Ignoring navigate() call: FragmentManager has already saved its state

When you get your auth callback, test if your app is in foreground and if so, navigate. Do nothing if your app is in background.

In the onResume method of the splashscreen, test if your user is authenticated. If so, skip your splashscreen.
