foreach (var message in page.Data.messages) Debug.Log(message.text);
// Continue only on an explicit action using page.Data.nextCursor.
// Local delivered history can outlive the small current server window.
// For send/report, import the SDK ChatExample and preserve its original
// operationId, issuedAt, channel and text before one explicit send.
// An uncertain outcome never permits a fresh identity or implicit retry.
}
}SDKs save received history on the device, separately from the live server window. Account changes hide it; only explicit local deletion clears it. see the quickstart
