Using NavigationPage in a TabbedPage with Prism and Xamarin.Forms

I am using Prism in my Xamarin.Forms app and for some reason OnNavigatedTo is not being called on the other pages in my TabbedPage. It seems to be because I am using navigation pages for each tab, but I looked through the docs, the Github page, the forums etc and I can't seem to find the correct way to make it work. Has anyone had any luck getting this to work properly?

TabsPage.xaml:

<?xml version="1.0" encoding="UTF-8"?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:prism="clr-namespace:Prism.Mvvm;assembly=Prism.Forms" prism:ViewModelLocator.AutowireViewModel="True" xmlns:views="clr-namespace:MyApp.Views" xmlns:local="clr-namespace:MyApp;assembly=MyApp" x:Class="MyApp.Views.TabsPage">
    <TabbedPage.Children>
        <NavigationPage Title="Tab 1">
            <x:Arguments>
                <views:HomePage />
            </x:Arguments>
        </NavigationPage>
        <NavigationPage Title="Tab 2">
            <x:Arguments>
                <views:SecondPage />
            </x:Arguments>
        </NavigationPage>
        <NavigationPage Title="Tab 3">
            <x:Arguments>
                <views:ThirdPage />
            </x:Arguments>
        </NavigationPage>
        <NavigationPage Title="Tab 4">
            <x:Arguments>
                <views:FourthPage />
            </x:Arguments>
        </NavigationPage>
    </TabbedPage.Children>
</TabbedPage>

TabsPage.xaml.cs:

using Prism.Navigation;
using Xamarin.Forms;

namespace MyApp.Views
{
    public partial class TabsPage : TabbedPage, INavigatingAware
    {
        public TabsPage()
        {
            InitializeComponent();
        }

        public void OnNavigatingTo(NavigationParameters parameters)
        {
            foreach (var child in Children)
            {
                (child as INavigatingAware)?.OnNavigatingTo(parameters);
                (child?.BindingContext as INavigatingAware)?.OnNavigatingTo(parameters);
            }
        }
    }
}
