HPS - Only pulling Old Invoices from API

On the work order costs endpoint, we get records for recent work orders (e.g., Work Order No. LCCH0264; Work Order Id 237824). However, we no longer get the associated invoice information (e.g., Invoice Number, Invoice Date, etc.) after 2022-12-08. Was there an integration change that may have caused the information to no longer be connected between invoices and work orders?
