UPDATE (22.03.2023): Since mid-December, no payments could be sent via Outbank for DKB accounts. The reason for this feature limitation is a technical issue at DKB. DKB has confirmed to us on several occasions that they would fix their FinTS problem by week 10. Unfortunately, this did not happen as agreed.
Since DKB has not provided us with a new date even after repeated inquiries, we have integrated SEPA transfers via another interface (in version 3.6.3). This workaround is unfortunately not as convenient as the known FinTS solution. Scheduled payments, standing orders, and direct debits are currently not available via this interface.
As soon as the DKB fixes the error in its system, we will switch back to the FinTS interface.
