Differences in app development in Studio Web

• In Studio Web, you add controls to an app by selecting the Toolbox icon below the Project Explorer icon, in the left-hand pane of the window, as opposed to selecting Add control in the standard Apps interface.
• Apps in Studio Web do not support rules. Use Studio automations triggered by events instead.
• Apps can only execute unattended automations using serverless robots.
• Apps do not currently support import and export of individual pages.

For more information on current limitations, refer to the Known limitations section of the Studio Web documentation.
