Outage Details

We are currently experiencing reduced approval rates for transactions requiring 3D Secure (3DS) challenges due to an issue with a third-party provider. This may result in more transactions than usual being declined during the authentication process. Our team is actively monitoring the situation together with the provider and will provide updates as soon as more information becomes available.
