   Thanks @cornelk  feedback,  @jiazhai maybe this is not a bug.
   
   In the first send, we can't read the message, because the reader `StartMessageID` option is `LatestMessageID()`, so in the second send, this reader should also not receive messages, right?
   
   Please refer to the following code:
   
   ```
   reader1, err := client.CreateReader(ReaderOptions{
   		Topic:                   topic,
   		StartMessageID:          EarliestMessageID(),
   		StartMessageIDInclusive: false,
   	})
   
   	ctx, cancel = context.WithTimeout(context.Background(), 5*time.Second)
   	msg, err = reader1.Next(ctx)
   	assert.NoError(t, err)
   	assert.NotNil(t, msg)
   	cancel()
   ```
