Welcome to QuickBooks Community, @RandikaJeewantha.

I'll share some information about the custom validation message. You'll want to re-sync the web connector again. This process will also reinstate the updates with QuickBooks. Let me guide you how.

1. Open the QuickBooks company file.
2. Close any open window such as the employee center or company settings.
3. Re-open Web Connector.

With the above steps, you're able to view the custom validation message again. For more recommended troubleshooting steps, check out this guide: Fix common Web Connector errors in QuickBooks Desktop.
