You can workaround this issue by overriding the method that resets the culture on iOS and Android.

Go to AppDelegate.cs inside the iOS project and add an EmptyLocalize class which implements our ILocalize interface and basically overrides the default logic for resetting the culture:

public class EmptyLocalize : ILocalize
{
    public CultureInfo GetCurrentCultureInfo()
    {
        return CultureInfo.DefaultThreadCurrentUICulture;
    }

    public void SetLocale(CultureInfo cultureInfo)
    {
    }
}

ILocalize is from the Telerik.XamarinForms.Common namespace.

Register the EmptyLocalize class above the namespace:

[assembly: Xamarin.Forms.Dependency(typeof(MyXamarinApp.iOS.EmptyLocalize))]

The workaround can be applied on Android as well  - add the same EmptyLocalize inside the MainActivity.cs and register it in a similar way:

[assembly: Xamarin.Forms.Dependency(typeof(MyXamarinApp.Droid.EmptyLocalize))]
