In this tutorial we will walk you through how to add a logo to your Listing Layout / Design.
Firstly click on "Design Library" in the left hand menu.
Scroll down and in your library, you should have the "Universal-layout" installed.
Simply click "Settings" on this.
From here, you can clip "Upload your logo" to add it into your design.
This will update all live designs automatically so no need to re-add your design to all listings.
