Alert not shown in OnAppearing method

[Legends]

Description

I have overriden the OnAppearing method in MainPage.xaml.cs:

protected override async void OnAppearing()
{
	try
	{
		await this.DisplayAlert("Title", "Message", "OK");
		...
		..
		.
		}
	catch (Exception ex)
	{
		throw;
	}
}

Two things:
1.) The alert is not shown
2.) Perhaps 1.) is ok, because probably called too early in the page lifecycle? But shouldn't there be a way to inform the user, that it is too early to call the DisplayAlert method at this stage?
