Reports are broken down into two categories, “Global“ and “Personal“. “Global” reports can be viewed by any user with the correct permissions, whereas “Personal“ reports can only be viewed if you are the owner or a member of the report.
To view an existing report, first navigate to the “Reports” page using the menu on the left. This automatically shows all global reports available for you to see.
You can view any of them using the “View“ button to the right of the page.

Clicking on the “Personal” tab along the top will show you any report you are the owner or member of. These can be viewed in the same way.
