paypal express does not update all transactions... we get this message that does not make sense
Problem encountered when trying to process a payment on behalf of "D B I" https://db.org/. (I changed both to just Initials for privacy)
Please re-check your payment settings.
10412 Duplicate invoice. Payment has already been made for this InvoiceID., 11452 Merchant not enabled for reference transactions. Merchant not enabled for reference transactions

What do we do?
How do we know where to find the invoice?
