For a status to be read, it must have been delivered. In some scenarios, such as when a user is in the chat screen and a message arrives, the message is delivered and read almost simultaneously. In this or other similar scenarios, the delivered notification will not be sent back, as it is implied that a message has been delivered if it has been read. The reason for this behavior is internal optimization.
