Thanks for your idea, merelyn sunday.

While our engineers are still working to resolve this issue, you can continue manually unlink the invoice, since it works on your end. After that, delete the unlink invoice and then create a new one. That new invoice will be the one you're going to link to the estimate.

On the other hand, as my colleagues mentioned above, you will be receiving an update via email once this is resolved.

Keep in touch with me if you have any concerns with your QuickBooks account.
