Hello, guenther93. Thanks for letting us know about the issue you're experiencing with the QuickBooks Online (QBO) mobile app. It’s possible that this could be related to the app's data. Let’s work through some troubleshooting steps to get the app running smoothly again, so you can create invoices without interruption.
Before we proceed, could you please share the exact tax code error you’re encountering while updating or creating invoices? This information will help us identify the root cause and provide the most effective solution.
Should the error stems from the data in your mobile app, we recommend clearing the app's data to refresh the system and eliminate outdated files causing the behavior.
For Android devices, here are the steps:
- Go to Menu, then tap Settings.
- Select Refresh Data.
- Choose Yes to confirm.
For iOS devices, follow these steps:
- Go to Settings, then tap General.
- Hit iPhone Storage and select the QuickBooks Online app.
- Choose Offload App.
If the issue persists, we'd recommend uninstalling (tap and hold the app icon) and reinstalling the app. This is to ensure the version you'll be using is updated.
If there's anything else we can assist you with, please feel free to reach out to us.
