Hello there, @userryan3.
I'm here to help you fix the issue of why you're unable to see your customers' contact list in the QuickBooks Online (QBO) mobile app.
One of the possible reasons why you encountered some unusual behavior with your customer list is that your app is full of cache. The app often keeps a cache to speed up your experience while performing your tasks. Another reason might also be caused by an outdated app. That said, let's perform some troubleshooting steps to fix these issues.
We can start by refreshing the data within the app or from the settings menu on your mobile app. This refreshes the application to remove the older cache that causes this odd behavior.
For Android:
- Go to the Menu ☰ then click the Gear icon.
- Select Refresh Data.
- Tap Yes.
For iOS:
- Go to the Menu ☰ icon, then select Help & Feedback.
- Tap Refresh Data.
- Select Refresh.
If the issue persists, I suggest uninstalling and then reinstalling the mobile app. It allows you to use the app on a clean slate. Follow the steps below to proceed:
- Tap and hold the app on your phone.
- Drag the app to the Uninstall section.
- Select Yes to confirm.
Once done, visit these links to reinstall the QBO mobile app:

If the problem continues, I recommend reaching out to our Technical Support Team. They're equipped with the necessary tools to perform a screen-sharing session to conduct further investigation into this behavior.
