To view your statements, navigate to Owner Statement in the menu, and then select either monthly or annually.
Within the monthly statements page, you can pick between all your units at the top using the Unit Chooser, and then select the month and year you would like to view.
Every time you change the month, be sure to hit the blue "Refresh" button to apply the changes.
The annual statements work the same way, but instead of month-to-month it'll show you the entire calendar year selected.
