After creating a workflow, you will need to activate it before it can trigger for your users. Inactive workflows will show a red dot under the Status column to indicate inactive. This dot will change to green when the workflow is activated.
Step One: Navigate to Share>Workflows from the navigation bar
Step Two: To activate your Workflow click the Pencil icon and then click the Activate link to set the status to active
Your workflow is now active and will trigger for any users who meet your audience and criteria settings.
