Do you encounter a prompt or error message when scanning your receipts? If so, this will help me provide a solution that fits your issue.
In the meantime, you can perform app troubleshooting, as an issue with the QuickBooks app can affect how it functions.
If you're using Android, clear the software data by going to Settings > Apps > QuickBooks app > Storage > Clear Data.
For iPhone, go to Settings > App > iPhone Storage > QuickBooks App > Offload.
If the problem continues, you can uninstall and reinstall the QuickBooks app to ensure it functions properly.
Alternatively, you can sign in to your QuickBooks Online (QBO) account using a web browser and upload files from your computer or Google Drive.
