Description

NOTE: I would also like to bring one issue that happening in iOS when we are navigating between pages which have bottom tab and that don't , For example in the below mentioned sample click on monkey tab and select any monkey in the list and once we are monkey detail page click on monkey details we will navigate to subpage then click on go back button , you will notice that bottom tabs are invisible for the monkey detail page even though TabBarIsVisible is set ti true , This happens one when you Shell.Current.Navigation.PopAsync(false) for Shell.Current.Navigation.PopAsync(true) the tabs are visible after some delay.

Steps to Reproduce

1. Xamarin_Forms___Xaminals.zip
2. Download the above sample
3. Click on Monkey tab and then click any monkey in the list then we will route to Monkey details
   4 Once on the Monkey Detail Click on the page then we will navigate to Subpage there click on Go Back
   5 You will be back on Monkey Detail page with out tabs even though TabBarIsVisible is set to true

Hi, @Srikanth540-L - thank you so much for submitting this issue! We'll work to fix this :)

In the meantime, a temporary workaround would be to reenable the popasync animation. So in your SubPage code-behind, if you remove the bool so that you have await Shell.Current.Navigation.PopAsync(); instead of await Shell.Current.Navigation.PopAsync(false);, you should see the Bottom Tabs again. Hope this will work well for the time being!

This should be fix by the following PR

Hi @rachelkang , await Shell.Current.Navigation.PopAsync(); will solve the issue but there is delay when the tabs are visible but same is not happening when you use the back button in navigation bar which is inbuilt in the xamarin forms.
@PureWeen when this fix will be available in the xamarin forms updated version and has the fix been validated in the above sample before closing the issue ?
