To view the unsent invoices on the mobile app., @MartinM, you will need to clear the cache or reinstall the apps to resolve them effectively. Let me provide you with the steps so that you can access it.
To begin, we can initiate a data refresh either through the system or the settings menu. These will refresh the application and eliminate the outdated cache responsible for the unusual behavior.
- Go to the Menu ☰ icon, then select Help & Feedback.
- Tap Refresh Data.
- Select Refresh.

You can also do this on your phone settings. I'll guide you on how:
- Go to your phone's settings and click Settings.
- Next, select General and choose iPhone Storage.
- Look for the QuickBooks app and select Offload App. This will only free up the storage without deleting the documents and data of the app.
If the problem continues, I recommend removing and then reinstalling the mobile application. These will enable you to start fresh. To proceed, please follow the instructions provided below:
- Tap and hold the app on your phone.
- Drag the app to the Uninstall section.
- Select Yes to confirm.
- Once done, visit this link to reinstall.
