Some customers who have been with improveit 360 for a long time, may be used to seeing the Report Wizard tool, instead of the Classic Report Builder.
The Report Wizard is a tool Salesforce created to allow Mobile Users to build reports on the go, from a mobile device. The interface is not as intuitive for desktop as it doesn't feature any drag-and-drop functionality.
To turn off the Report Wizard, go to the User who is seeing the Report Wizard and uncheck the Accessibility Mode (Classic Only) checkbox.
Go back to the Reports Tab and the User should see the traditional Classic Report Builder tool.
