Is anyone else having issues with progress invoicing? I create invoices from estimates and can see the links. When I save and close, the links break.

We use Avalara's AvaTax connector to calculate sales tax. I have been working with both Avalara and Intuit to correct this issue. However, Intuit reports that this is a software limitation and cannot be fixed. Progress invoicing is integral to our process. Why is the link breaking simply because an API callout has added a sales tax line item? This is unacceptable.
