But sometimes it seems to get \"stuck\" that way on multiple levels. The button always works though.\r\n\r\nThe navigators are nested three deep. In the following code snippet I have removed all the irrelevant screens. So I'm concerned about \"Learn\" and \"DailyContent\" and \"DailyContentStage\". It is a bit confusing because DailyContentStage is a top-level component. \r\n\r\n![img_2426](https://user-images.githubusercontent.com/603598/32458408-444dc92e-c324-11e7-90cf-bb9c9c73ca32.jpeg)\r\n![img_2425](https://user-images.githubusercontent.com/603598/32458410-446dbd56-c324-11e7-8cf8-41636781fa07.PNG)\r\n\r\n```\r\n// this navigator contains the track tabs: Weight, Steps and Sleep\r\nconst LearnTabs = TabNavigator(\r\n  {\r\n    DailyContent: { screen: DailyContentContainer, navigationOptions: { tabBarLabel: 'Daily Content' } },\r\n    Recipes: { screen: RecipesContainer, navigationOptions: { tabBarLabel: 'Recipes' } },\r\n  },\r\n  {\r\n    tabBarComponent: TabBarBottom,\r\n    tabBarPosition: 'top',\r\n    initialRouteName: 'DailyContent',\r\n    tabBarOptions: { ...topTabBarOptions },\r\n  },\r\n);\r\n\r\n// this navigator contains the track tabs: Weight, Steps and Sleep\r\nconst TrackTabs = TabNavigator(\r\n  {\r\n    Weight: { screen: WeightContainer, navigationOptions: { tabBarLabel: 'Weight' } },\r\n    Steps: { screen: StepsContainer, navigationOptions: { tabBarLabel: 'Steps' } },\r\n    Sleep: { screen: SleepContainer, navigationOptions: { tabBarLabel: 'Sleep' } },\r\n  },\r\n  {\r\n    tabBarComponent: TabBarBottom,\r\n    tabBarPosition: 'top',\r\n    initialRouteName: 'Weight',\r\n    tabBarOptions: { ...topTabBarOptions },\r\n  },\r\n);\r\n\r\n// this navigator contains the main tabs: Home, Track, Chat, Learn, Settings\r\nconst MainTabs = TabNavigator(\r\n  {\r\n    Learn: { screen: LearnTabs, navigationOptions: { tabBarLabel: 'Learn' } },\r\n  },\r\n  {\r\n    tabBarComponent: TabBarBottom,\r\n    tabBarPosition: 'bottom',\r\n    initialRouteName: 'Home',\r\n  },\r\n);\r\n\r\n// this is the top-level app navigator\r\nconst AppNavigator = StackNavigator(\r\n  {\r\n    MainTabs: { screen: MainTabs },\r\n    DailyContentStage: { screen: DailyContentStageContainer },  // MainTabs/Learn/DailyContent\r\n  },\r\n  {\r\n    initialRouteName: 'Loading',\r\n  },\r\n);\r\n\r\nexport default AppNavigator;\r\n```\r\n\r\n\r\n\r\n### Expected Behavior\r\n- Back arrow should always be present as part of back button \r\n![img_2427](https://user-images.githubusercontent.com/603598/32458388-314cd0cc-c324-11e7-9332-2cd427b471a2.PNG)\r\n\r\nI guess it's something to do with the deep nesting but any and all thoughts welcome.
