What is User State and how do I use it?

User State shows the current state of users in the workflow (e.g. which node they are on, variables). On Manage there is a User State column/link; clicking it opens a view of all users and their details across that workflow. Use it to debug “stuck” users or to see which node a given phone number is at. There is also a consolidated User State view next to Add Workflow that shows usage across all workflows.
