How does Preview Mode differ from See Live?

Preview Mode: Displays the entire Whatfix experience that includes Self Help tab, widgets, walkthroughs, etc. It helps the content creator experience what the end user sees even if the Whatfix JavaScript or the Whatfix custom extension is not deployed. This is also the mode where you can check how Advanced customization and Smart Context works.

See Live: Is a preview of only the Walkthrough that the user is currently viewing. It does not display Self help, changes due to advanced customization, Smart context, etc.
