My invoices suddenly don't all show up in the QB mobile app - How is this fixed ?

Let me help retrieve those invoices on your QuickBooks mobile app, noesjahyland.

Performing some basic troubleshooting steps will resolve the issue while the application isn't fully functional.

To get this sorted out, as an initial step, let's clear the application's cache files. Doing so helps in fixing any sorts of unexpected behavior in the system.

Here's how:

1. Go to Settings and click Setting General iPhone Storage.
2. Choose an app that's taking up a lot of space.
3. To free up the storage without deleting the documents and data for the app, hit the Offload App.
    

Once refreshed, restart your mobile phone. Then, go back to the mobile app and check your invoices. If you get the same result, uninstall and reinstall the QuickBooks Online mobile app.

Additionally, you can visit this write-up: Compare mobile app features It provides you more information on what options you can access on the customers' and vendors' side as well as a chart to easily compare feature availability on supported devices.
