As part of consolidating our DHL products into a single menu, we have integrated the settings for DHL Preferred Delivery directly into the core. You can still find these settings under Setup » Orders » Shipping » Shipping service provider » DHL Shipping » Preferred delivery settings.
To complete this transition and prevent errors caused by duplicate integrations (Plugin and Core), the old plugin will be deactivated on 18 March 2026 (Beta: 04 March 2026, Early: 11 March 2026) as the core integration takes over.
No need to do anything: Since the settings have already been applied in the menu, you don't need to do anything.
