Upon checking here, we've received similar cases or reports about the error code: "Modifying this timesheet does not update the associated invoice. Do you want to continue?" (INV-112837).
If you haven't, I'd suggest contacting our QuickBooks support team to add you to the list of affected users and be informed promptly once the issue is resolved. Our product engineers are working diligently to provide a permanent fix so you can get back to business.
Here's how:
