Hi there, jackiechan.

I appreciate you bringing this issue to our attention. 

Let's try some basic troubleshooting steps to isolate this. Please make sure you have the updated QuickBooks Online (QBO) Mobile App installed.

Aside from updating the app to the latest version, you can try clearing its cache to resolve unexpected responses or outcome.

Here are the steps:

1. Log out of the QBO app.
2. Go to your phone settings.
3. Select Applications.
4. Locate QBO and click on Clear Data and Cache.
5. Restart the phone and log back in to the QBO app.

If the same thing happens, let's uninstall and reinstall the app. You can follow the detailed steps in this article: Download the QBO Mobile App.

Please let me know how it goes by leaving a comment below. I'm here to help. Have a good one.
