The Reporting (Beta) screen will eventually replace the legacy Reporting screen and will include a host of new and improved reports. The features and reports on this new screen will be rolled out in stages across several consecutive releases.
The My reports section, in the Reporting (Beta) screen, contains a list of custom reports that you have generated.
From here you can:
Search for a particular custom report using the search bar and filters
Rerun a custom report you’ve previously created
