Note: Enabling roles can only be done by Workspace or Company Admins.
Once a role is created, it must be enabled in a workspace. Once the role is enabled, you will be able to assign the role to tasks and milestones and assign workspace members to the role.
To enable a role in a workspace, navigate to the workspace and select Settings>General Settings>Project Roles. On this page, simply begin typing the name of the role you wish to add in the box to the right of "Workspace Roles" or use the magnifying glass icon to choose from a list of all available roles.
Once you have selected all the roles you wish to enable, select Update to save your changes.
