Hello there, Laura.
Refreshing and updating the data in your apps are the troubleshooting steps to ensure you can successfully send invoices to your customers without any issues.
Here's how you can refresh your data on various mobile operating systems:
For Android devices:
- Go to the Menu ☰, then tap More Options ⋮.
- Select Settings, then Refresh Data.
- Click YES to confirm.
For iOS devices:
- Go to Settings, then tap General.
- Select iPhone Storage, then tap the QuickBooks Online app.
- Tap Offload App.
These will free up the storage without deleting your app's documents and data.
If you have completed this step and the issue persists, I recommend uninstalling and reinstalling the application to ensure compatibility and proper functionality.
In the meantime, you can send invoices using the web browser. This way, you can efficiently continue managing your invoices.
