I tried upgrading to Xamarin Forms 4, but immediately went back to 3. I am using simple navigation with NavigationPage, using:
NavigationPage.TitleIcon="transparent.png" in the ContentPage header element. As you can probably guess, transparent.png is a transparent image.
But after upgrading to 4, I am getting a default Xamarin icon on the navbar. I do not want an icon there, but I can't figure out how to get rid of it in Forms 4.
