   We are experiencing elevated failures on some **Mastercard and Maestro** card payments due to a **third-party issue with the Mastercard Debit network**. SumUp systems are operating normally; some transactions may fail until our payment partners complete their recovery. We are monitoring the situation and will update this page as it changes. Please retry failed payments after a few minutes. We apologise for any inconvenience.
