Hi, 

I'm currently doing the walkthrough for "Lightning Experience Customization". On the section of "Create a Custom Detail Page Button", I am trying to create a new button called "Map Location". The issue is that after I create the new button and add it to the page layout, it is not showing up. 

Trailhead says I should "Expand the actions menu, and select Map Location." but when I do that, it does not appear. 

I have already updated the page layout so I don't know why it isn't showing up. 

Thanks,

Joe
