Issue generating manifests for Royal Mail international services

We have identified an issue with generating manifests for international services. We are working with Royal Mail to understand the root cause and implement a fix. Failed manifests are reported to our support team who will resubmit the manifest as soon as a fix is deployed. If you are impacted you will notice that you are unable to download the sales order summary report. This is being worked on as a matter of urgency. We will update this incident as soon as we have more information.
