SwitchNavigator rotates orientation even when it is locked

[vladinko0]

Current Behavior

When I launch application it is rotated to Landscape and then quickly back to Portrait mode.

Expected Behavior

I want to make it stable in Portrait mode on launch. But I cannot lock whole project to Portrait, because on some screens I need Landscape orientation.
This issue is not caused by react-native-orientation-locker module, because when I am not using routes.js file it locks the screen to Portrait without any rotation.

How to reproduce

App.js

import React, { Component } from 'react';
import Start from './routes'
import Orientation from 'react-native-orientation-locker';

export default class App extends Component {
  constructor(props) {
    super(props);
} 
 componentDidMount() {
    Orientation.lockToPortrait(); 
  }
  render() {
    return (
      <Start />
    );
  }
}

routes.js

import { StackNavigator, SwitchNavigator } from 'react-navigation';
import AuthLoadingScreen from './authloading'
import LoginScreen from './loginScreen'
import AppScreen from './appScreen'


const AuthStack = StackNavigator({
    Login: LoginScreen
});

const AppStack = StackNavigator({
    App: AppScreen
});


export default SwitchNavigator(
    {
        AuthLoading: AuthLoadingScreen,
        Auth: AuthStack,
        App: AppStack        
    },
    {
        initialRouteName: 'AuthLoading',
    }
);

authloading.js

import React from 'react';
import {
  View,
  Text
} from 'react-native';
import Orientation from 'react-native-orientation-locker';

export default class AuthLoadingScreen extends React.Component {
  constructor(props) {
    super(props);
  }
  componentDidMount() {
    Orientation.lockToPortrait(); 
  }

  render() {
    return (
      <View >
            <Text>Auth Loading</Text>
      </View>
    );
  }
}

It was my fault.
One of my screen contained this error prone code:

const setLandscapeRightOrientation = Platform.select({
    ios: Orientation.lockToLandscapeRight(),
    android: Orientation.lockToLandscapeLeft(),
});
