In an effort to provide a more sustainable training lab experience, our lab server uses a version of SharePoint that does not support the User Profile Service. Not having the User Profile service available is unfortunate, however, it ensures that the lab environment runs much smoother with far fewer issues ( and up-time is always a good thing!).
Although the User Profile service is not available, please take note of how it is used in the videos just in case your organization has that workflow action available. Otherwise, you can skip any step that mentions the User Profile service. We are sorry for any confusion!
