My mileage has stopped tracking altogether. How do I get it to fix ?

Hi there, Nicky. 

I'm here to help you fix your mileage tracking issue so you can get back on tracking them in the QuickBooks Online mobile app. 

Since you're having problems tracking them in the app, let's ensure everything is set up on your device. First, you'll have to sign in as a user with admin privileges to track mileage. After, you can review the setup and check if the auto-tracking option is enabled. You can follow the steps below for Android devices:

1. Open the QuickBooks mobile app.
2. Select the menu ☰ icon.
3. Select Mileage.
4. Turn on the Auto-tracking switch.

Once done, you can check your device's location settings. If you're using an Android device, you can use Google's steps to ensure the program can run in the background. 

The next step is disconnecting or disabling your hotspot while driving. Please know that Wi-Fi Hotspots can interfere with the trip recording, which results in inaccurate mileage tracking.

Now, you can review if the app is tracking miles. Here's how:

1. Select the menu ☰ icon.
2. Select Settings ⚙.
3. In the Mileage section, select Mileage Settings.

Review the list in the Avoid Missed Trips section. If all the settings have a green check, you're good to go. However, if you see a (!), follow the on-screen steps to make some adjustments.

Moreover, if the issue persists, you can follow Step 5 to Step 9 of this article for more troubleshooting steps: Fix mileage tracking issues in the QuickBooks Online mobile app.

Additionally, you can add a trip manually in QuickBooks Online for the trips that aren't recorded and tracked.
