   We identified an issue that caused historical data generation for March 26th to fail. A reprocessing job is currently underway. No data has been lost, and data is gradually becoming available in both the platform and API. We expect full availability within the next 1-2 hours. We’ll provide an update once processing is complete. Message injection and outbound message delivery are not impacted - all messages are flowing as expected.
