eCom is designed so that you can review your changes to your eCom store without having to publish them. This article explains how to do this using the process of adding a logo as an example. All themes have many ways to customize them, and these customizations go far beyond adding a logo. This article explains previews, in particular using the Conform Plus theme. These instructions may be different for other themes
In your eCom admin, go to Design.
โSelect Customize theme.
Select Logo at the bottom of the Header options in the General tab.
Select Browse under Logo.
Locate and open the logo image on your computer. If you like the preview of your logo, select Publish changes. If not, select the option arrow > Remove changes.
