Thank you for clarifying your concern, @kendra-devoscoun.

I want to ensure your issue about sorting invoices by date in the QuickBooks Self-Employed mobile app gets resolved, and I'd like to redirect you to the best support group available to get this address right away.

Resetting the app's data and uninstalling and reinstalling the app should fix the issue. Since these troubleshooting steps didn't resolve your problem, I highly recommend contacting our QuickBooks Support Team. They can further check on this matter and provide in-depth troubleshooting steps to get this fixed. They can also create an investigation ticket if most users are experiencing the same.

To reach them, you can follow the detailed steps shared by my colleague Charies_M above.

Once everything is resolved, you can continue working on your task using the QuickBooks Self-Employed mobile app. If you also want to track mileage automatically, you can learn more through this article: Automatically track mileage in QuickBooks Self-Employed.

You can update me here in the Community on how things go. I'll be more than happy to assist you again, @kendra-devoscoun. Have a great day and take care always.
