Orders Seller 1, where the MKT an FFMT is in the same account, has no notifications on Hook type FromOrders for the state "Payment-Approved".

The S3 is not saving this status, and due that the notifications are not being sent.

Make sure that Hook setup has the type configured as FromOrders and the state payment-approved on filter. Generate an order type seller 1. No notifications will be sent.

Confirm on Splunk logs.

If possible the client can use the type "FromWorkflow". At this type the notification is OK.
