We resolved an issue where some Prep flows that appended to a published data source showed fewer records than expected in the output data source. We applied a fix and restarted affected services. Affected customers can run a full refresh with the Create output option to refresh the data source. We apologize for how this incident affected you and your business. We will undertake a full investigation of the incident, establishing the technical trigger, the underlying cause, and preventive action to avoid a repeat in the future.
