-> [!WARNING]
-> Due to [platform limitations](https://github.com/microsoft/microsoft-ui-xaml/issues/1494) on Windows only, a default back button icon is not provided out of the box. You will need to provide your own icon on each instance of the `NavigationBar` where you want to display a back button. On Android and iOS, the native default back button icon is used. On all other platforms, a back button icon is bundled in the default styles for the `NavigationBar`.
+> [!NOTE]
+> The default back button icon can be customized for non-mobile platforms by overriding the `NavigationBarBackIconData` resource. On `Android` and `iOS`, the native default back button icon is used. On Windows and other non-mobile platforms, you can provide a custom back button icon by defining the `NavigationBarBackIconData` resource in your resource dictionary:
+>
+>```xml
+><Application.Resources>
+>    <x:String x:Key="NavigationBarBackIconData">YOUR_CUSTOM_PATH_DATA</x:String>
