(8)Account servicing payment service providers that offer a dedicated interface and that have implemented a contingency mechanism as set out in Article 33(4) of Delegated Regulation (EU) 2018/389 should not be required to implement the new mandatory exemption in their direct customer interfaces for the purpose of the contingency mechanism, provided that they do not apply the exemption laid down in Article 10 of Delegated Regulation (EU) 2018/389 in their direct customer interfaces. It would be disproportionate to require account servicing payment service providers that offer a dedicated interface in which they have to implement the new mandatory exemption, to also implement the exemption in their direct customer interfaces for the purpose of the contingency mechanism.
