If unable to view fees on work items or kanban, check that you have the proper settings turned to enable viewing dollar amounts (vs. just time). To review your permissions, go to your User Profile by selecting your name from the main menu. Review your given permissions under the Permissions section and update your permissions (only if an Admin) by editing your profile.
Not an Admin? Request from one of your admins to grant you access to View Dollar Amounts. They can easily update your pemissions by going to: Settings > Colleagues, selecting your name from the Colleague list and update the setting called View Dollar Amounts.
Once access is granted, you will be able to view dollar amounts on individual work items and on the work kanban board.
