We regret that this longstanding issue has still not been resolved. Unfortunately the rebuilding of aggregate data from a range of sources is a delicate operation and we are committed to ensuring that the result is absolutely accurate. In consideration of the scale of the impact and the delay in resolution, we have made the decision to track further progress at https://help.nexmo.com/hc/en-us/articles/360001020387
in the Current Known Issues section of our Knowledgebase rather than as an incident. You can follow updates by subscribing to that article.
