I recognize the importance of viewing your uploaded bills in the QuickBooks Online (QBO) desktop app, kdworley21. Let me share some information and guidelines about this matter.
Before anything else, can you share the error message you received and the device you used when accessing the uploaded bills?
Also, let's perform a troubleshooting to enhance the performance of your app. This way, it'll aid in eliminating any stored data on the app and restore it to its original functionality.
Change the Wi-Fi data connection on your device.
Power down and restart your device.
Uninstall and then reinstall the QBO Apps.
Alternatively, you can also view your uploaded bills using a web browser or from the QuickBooks Online desktop app.
