I have a back button implemented like so:
<Button x:Name="BackButton" Click="Back_Click" Style="{StaticResource NavigationBackButtonNormalStyle}"/>
This worked fine until upgrading to Uno 3.1. Now my back button shows as a box with a question mark inside of it. I believe this means it is not able to find the font. I did upgrade to the uno-fluentui-assets font as mentioned in the documentation. How do I make this work now? If someone has a suggestion of another approach to putting a back arrow on a button- I would be fine doing that as well. Thank you.
