I'm currently learning Xamarin Forms and I have a small graphic issue. I have to fit the height of all the buttons to 100% (based on Navigation bar). Actually Xamarin cut some pixels in the bottom for the hamburger icon and the "three dots" icon is not set to 100% height.
I'm using the default template Master-Detail installed by Visual Studio, the issue it can be reproduced by creating the Master-Detail template in your app
