Resolved: All affected customers' billing data is now up to date, and data updates are running normally. A change to our billing data processing, deployed on the evening of Nov 3, caused overnight data updates to time out for a subset of customers. We reverted the change the next morning and re-ran the affected customers. Your cost data was not lost or changed, and no action is needed on your end. We apologize for the delay and are reviewing how we roll out changes like this.
