Why didn’t it track my miles all day yesterday

Thank you for reaching out to us, @edwardslana880-g.

Welcome to the Community. I'd be glad to help you fix your mileage tracking issue.

If you turn on mileage tracking in the QuickBooks Self-Employed app, it automatically records your work trips.

Since there are missing trips on your account, you can adjust your Android device and your app settings so your trips are tracked accurately. 

Here's the first step fixing the issue:

1. Review the general location settings on your phone.
2. Make sure that running QuickBooks Self-Employed app is allowed to run in the background.
