App not working

Welcome to the Community, @danzai.

I'll help you with the issue you're having with QuickBooks Online app.

It is an unusual behavior of your app. Thus, I recommend resetting your app data to refresh your connection.

Here's how:

For Android devices

1. Go to the More Options.
2. Select Settings.
3. Click Refresh Data.
4. Then select Yes.

For IOS

1. Go to the Menu ☰.
2. Select Help & Feedback.
3. Click Refresh Data.
4. Then select Refresh.

If you still have the same issue after refreshing the data, you can uninstall and reinstall the app. Then restart your phone. Refer to this article for the steps: uninstalling and reinstalling the app.

Let me know if you have questions about the QuickBooks app. I'm always here to help. Have a great day.

Don't use the app. It is quite simply not worth even looking at. Open Quickbooks in a web browser and just log into your account.
