Looking at the API logs, it appears that there were subsequent POST requests to certify the beneficial-ownership after the initial certification. Currently, this negates the previous certification and sets them back to recertify. To avoid this, we recommend implementing logic that only calls the endpoint to certify beneficial ownership when the certify-beneficial-ownership link is available.
The beneficial ownership status for this customer is currently “certified” so you should be all set for this customer
