PopAsync clear all pages on Navigation Stack (1.1.0-pre2)

See original GitHub issue

If i pop a normal page after pop a popup page like that:

await PopupNavigation.Instance.PopAsync();
await Navigation.PopAsync();

An exception raise at Navigation.PopAsync because after i pop the popup page, the Navigation Stack is empty. But if i exchange order of method like that:

await Navigation.PopAsync();
await PopupNavigation.Instance.PopAsync();

The app works normaly. I’m using Xamarin.Forms 2.4.0.282.

@Lincolnerson These issues are only about Pg.Plugins.Popup, not about Xamarin.Forms. You can create an issue here (https://github.com/xamarin/Xamarin.Forms/issues) or here (https://bugzilla.xamarin.com/)

Hi, I am going from Page 1 > Page 2 > Page 3 Once process is completed I am using following code to return on Page 2: Navigation.RemovePage(Navigation.NavigationStack[Navigation.NavigationStack.Count - 1])

Then again from Page 2 moving to Page3, but this time same above code is throwing below exception: UNHANDLED EXCEPTION: 02-05 17:00:39.083 I/MonoDroid( 1102): System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. 02-05 17:00:39.083 I/MonoDroid( 1102): Parameter name: index 02-05 17:00:39.083 I/MonoDroid( 1102): at System.ThrowHelper.ThrowArgumentOutOfRangeException (System.ExceptionArgument argument, System.ExceptionResource resource) [0x00029] in <896ad1d315ca4ba7b117efb8dacaedcf>:0 02-05 17:00:39.083 I/MonoDroid( 1102): at System.ThrowHelper.ThrowArgumentOutOfRangeException () [0x00000] in <896ad1d315ca4ba7b117efb8dacaedcf>:0 02-05 17:00:39.083 I/MonoDroid( 1102): at System.Collections.Generic.List1[T].get_Item (System.Int32 index) [0x00009] in <896ad1d315ca4ba7b117efb8dacaedcf>:0 02-05 17:00:39.083 I/MonoDroid( 1102): at CTS_CPR.View.Test.AcceleroMeterFinal.OnButtonPressed () [0x0002a] in D:\WorkSpace\Mobile\CPR\CTS-CPR\CTS-CPR\CTS_CPR\View\Test\AcceleroMeterFinal.xaml.cs:192 `

I also tried ‘Navigation.PopAsync()’ but still getting same issue. My main concern is this both code remove all pages from stack during second time when i come from Page 2 to Page3
