Hi there, Dallbones.
The QuickBooks Online (QBO) app is a mobile application that allows you to manage your business finances on the go.
As a result, you can only access limited types of reports in the QBO app, like the Profit and Loss report and Balance Sheet.
As a workaround, you can view the Aged Debtors report using our QuickBooks Online web browser.
You can also refer to this article and learn how to match your ageing reports in QBO.
Please respond to the forum for additional questions in managing reports.
