Prism Xamarin Forms INavigationService GoBackAsync not returning to previous page

Question

May be because I am new to Prism and to Xamarin Froms because of which I am facing a basic issue with the navigation.

Let me start with the details of my implementation and then the issue at hand.

1. I have a MasterDetail Page (named Home) which is my main page.
2. There are a few menu items in the Master Page. One of them is Partner.
3. On Click of Partner menu item, NavigationService.NavigateAsync("Navigation/Partner") method is called. Where "NavigationService" is of type "INavigationService".
4. This opens a page called "Partner" which is a tabbed page (TabbedPage). The first tab is a contentpage called "PartnerAll".
5. PartnerAll page contains a listview. On click of a list view item, a new page is opened "PartnerDetails" by calling NavigationService.NavigateAsync("Navigation/PartnerDetails", parameters, false, true);
6. On PartnerDetails page there is a "Cancel" button. On click of this button, I call await NavigationService.GoBackAsync(null, false, true);

Issue: When I call GoBackAsync, nagivation does not happen to the PartnerAll tab of Partner page. PartnerDetails page remains open.

Where is it I am going wrong. What should I do to make it work?

Please assist.

In point 5. you created new navigation page with new root page PartnerDetails and there is navigation stack with only one page, nothing to pop off.

Change:

PartnerAll page contains a listview. On click of a list view item, a new page is opened "PartnerDetails" by calling NavigationService.NavigateAsync("Navigation/PartnerDetails", parameters, false, true);

To:

PartnerAll page contains a listview. On click of a list view item, a new page is opened "PartnerDetails" by calling NavigationService.NavigateAsync("PartnerDetails", parameters, false, true);
