I think, in UWP should be possible to place pivot header to bottom. I read, we can do this without template editing. I cannot find any example.
Thanks for answer

Header placement. Headers can be placed at the top or the bottom of the screen.
If I understood you, default behavior like picture bellow
So, just use this Style for Pivot
<Style x:Key="PivotHeaderBottomStyle" TargetType="Pivot">
<Setter Property="Margin" Value="0"/>
<Setter Property="Padding" Value="0"/>

and your Pivot will be like this
Looking at the Pivot class here there isn't any property to move the pivot header to the bottom, so the example that you found is just a hint to how to use a pivot properly.
But at the end you need to edit the template.
