   Marqeta engineers identified and resolved an issue affecting the handling of some Mastercard messages. Since then, there has been no ongoing impact, and message processing is operating normally. A subset of Mastercard transactions may have been affected during the period the issue was present that will require some data remediation. We are reviewing the scope of this work and will communicate further if there are any steps to take action on by customers.
