The customer reports section can be only emailed. Download links are hidden in an effort to transition to make all of the reports available only through email.
View and export your customer base data within the Settings > Exports section at the top of your ReCharge Dashboard. From here you can track your subscriber growth trends. This will include lifetime data and will not be date-specific. To export reports, scroll down to the bottom of this page and click the report you want. It will be emailed to you as a CSV file.
