You can switch the status from the top-right menu on the rule detail page. Select "Enable" or "Disable."
Note: Disabling a rule stops all restrictions and message display for every product the rule is applied to.
To create a new rule based on an existing one, select "Duplicate" from the menu on the rule detail page. The duplicated rule is automatically named "Copy of [original name]." Rename it as needed.
You can delete a rule from the top-right menu on the rule detail page.
Note: Deleted rules cannot be restored. Before deleting, verify which products the rule is currently applied to.
