Shell navigation back is not working after update 2 NuGet packages 'Microsoft.Maui.Controls' and 'Microsoft.Maui.Controls.Compatibility'

[bhuwancb99]

Description

<PackageReference Include="Microsoft.Maui.Controls" Version="8.0.72" />
<PackageReference Include="Microsoft.Maui.Controls.Compatibility" Version="8.0.72" />

After updating these two packages to the latest versions, Shell navigation's back functionality stopped working. When clicking the back arrow button, nothing happens, and it gets stuck. It works fine with version 8.0.72, but after updating to the newer version, it's no longer functional.

Steps to Reproduce

add button inside page

<Button Grid.Row="2" x:Name="Btn_MonthlyPointReport" 
    Clicked="Btn_MonthlyPointReport_Clicked"
    Text="{x:Static resources:GlobalResource.MONTHLY_POINT}" 
    Style="{StaticResource ButtonStyle}"/>

when click on this button

 /// <summary>
/// Btn_MonthlyPointReport_Clicked
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
 private async void Btn_MonthlyPointReport_Clicked(object sender, EventArgs e)
{
    try
    {
        ShellNavigationState state = Shell.Current.CurrentState;
        await Shell.Current.GoToAsync($"{state.Location}/{nameof(StudentListPage)}");
    }
    catch (Exception ex)
    {
       
    }
}

I just want to check what versions are working and what are not. In the issue you have a few versions mentioned:

• 8.0.72
• 9.0 preview 7
• 8.0.82

Which version is having the issue?

[mattleibow]

Are you able to attach a repro where this is no longer working? This appears to be a case of a navigation from /mylocation to /mylocation/students. If you write the full path in the string for a test, does it work?

@bhuwancb99 Could you provide us with a sample project so we can investigate it further? Looking forward to your reply!

[bhuwancb99]

@jaosnz-rep - I have created a sample app, and it's working there, but it's not working in my mobile application. If you'd like, I can share my test APK along with the credentials.

Hi @mattleibow / @jaosnz-rep

I have now reproduced the issue, and it occurs when adding different <Shell.TitleView> elements inside a NavigationPage based on the pages (TitleView content change based on your requirement). The back arrow stops working with the mentioned NuGet packages. Please find the attached project for your reference.

any update on this ?

[QianaJiao]

Thanks for your sharing.
I just verified this issue on VS 17.11.3. It can be repro on Android platform with Maui 8.0.82, 8.0.80. And not repro on 8.0.72. It's a regression issue.

[mattleibow]

Were there any errors or messages in the logcat or output windows when navigating or when clicking back?

But thanks for the info and reports, we will have a look.

Tested on the latest release (8.0.90), and now it's working as expected. Thanks for fixing this issue!
