We are currently seeing long delays to items sent via the International Tracked and Signed service. These items have been collected from us as normal but in many cases are not showing any tracking updates. Having contacted Royal Mail this is likely due to a backlog of mail at Heathrow. As a result of the backlog items are not being scanned into the system until they are processed at Heathrow. Due to these long delays we have removed this service until we start to see it working normally again.
