Our Team has identified an issue that may have caused minor data loss to the Mailbox Provider statistics of our Advanced Stats service for a subset of customers between approximately 9/1/2020 4pm MT to 9/2/2020 1pm MT in both the UI and API. We have determined the underlying cause and have employed a fix. This issue did not impact any of our other stats or event reporting feeds. We apologize for any inconvenience this may have caused!
