This can be due to browser-related issues, tednithi. Let's work on some troubleshooting steps to fix this.
Corrupted files or data can prevent your system from loading correctly, which may hinder your ability to upload or download receipts. May I know if you receive an error when this happens?
For now, let's try refreshing your web browser to ensure you are viewing the up-to-date information, and log in and log out to reset your session with the QuickBooks server.
If the issue persists, try using a different QuickBooks-supported web browser to narrow down the issue.
