I am having the same issue. I try the fix described in this thread to no avail. Here's our summary of the issue:

- We added new products on August 1, 2022

- We deleted some discontinued products on the same date

- all our outstanding invoices that had the old product now show the product as "deleted"

- we change the old product to the new product in the hopes of resending the invoice for payment

- despite attempting the fix herein, we continue to get the error: "Select a date that's after the date you started tracking this inventory item."

How do we fix our issue?
