When I am changing the orientation of a device, the master page is behaving very strange. You can see that the white space on the left is appearing. Is it a known bug in Xamarin Forms? Does anyone know some workaround to prevent this strange behavior?
I reproduced this issue on my side and reported it in Github.
Set MasterBehavior = MasterBehavior.Popover; in the MainPage.xaml.cs constructor.
The issue seems to be with Xamarin.Forms (Ver.3.0.XXXXXX).
5. Clean and rebuild your project.
