May I know what error code or message you received when updating the invoices?
Additional details and screenshots would be much appreciated, too. Thanks in advance!
How are you doing, Mrdetailing? I hope you're able to update your invoices by now.
If the same error exists, we can do browser troubleshooting steps. Cache files might be causing the error when updating the invoices.
If the browser troubleshooting steps don't work, I'd recommend reaching out to our QuickBooks Customer Care Team to further investigate this.
We always appreciate the additional details that you can provide. This would help us know where to start the process in resolving your issue. Thanks in advance!
