I’ve been unable to add any milage details on my phone all softwares are up to date, the help section on here crashes as well please help.

Hi there, m-clarke9-btinte.

I’ll help make sure you can add mileage details on your mobile device. Let’s run the basic troubleshooting steps to get you back on track.

This unusual behavior you’re experiencing in QBO can be caused by the piled-up cache. We’ll have to remove them to boost the overall performance of the app.

For Android:

1. Select Settings and tap the Refresh Data option.
2. Click Yes to confirm the action.

For iOS:

1. Go to the menu or three horizontal lines icon.
2. Choose Help & Feedback.
3. Press Refresh Data and Refresh.
4.  

Next, open QBO again and add some information on your miles. If the issue persists, uninstall and reinstall to start fresh. Here’s an article that will guide you on how to get the online program: Download the QuickBooks Online mobile app.

Additionally, this article contains solutions on how to resolve errors when using the mobile app version. The troubleshooting is scenario-based, so make sure to select the one that fits your situation.
