PdfViewer Changes Culture on Android/iOS

[Patrick Kehr]

Hi, 
we have a Xamarin Contentpage, wich is Programmicaly built (Not Xaml).
When we use the PdfViewer the Culture of everything changes. 

Datepickers and other things like DateTime.ToString("d") change from "de" (wich is our Culture) to something Called Invariant Language(Invariant Country).

This only happens after we Initialize a PdfViewer.

We have a workaround wich only works on iOS:

CultureInfo _currentCulture;

public void InitPdfViewer() 

{

     _currentCulture = Thread.CurrentThread.CurrentCulture;
     _internalPdfViewer = new SfPdfViewer()

}

//Called when leaving Content Page

public void unloadViewer()

{

     _internalPdfViewer.Unload();

     Thread.CurrentThread.CurrentCulture = _currentCulture;

     Thread.CurrentThread.CurrentUICulture = _currentCulture;

}

We are using Version 18.3.0.35 and have tested this Bug on Android 9 Emulator  x86 and a physical iPad Air 2.

Why is the Culture Changing and how can we reliably fix it?
