Q:

UWP ScrollViewer and StackPanels don't work properly

The UWP ScrollViewer element isn't scrolling at all with my StackPanel. I've tried Grids and the row definitions but that didn't work either. Here is my current XAML.

(I apologize if this is a stupid question - I'm new to UWP development, also disregard me explicitly defining font size on the TextBlock)

A:

The frame I was calling navigate on was inside of a stackpanel and I never noticed it until now. I removed the stackpanel and scrolling worked with my original code.
