Blynk Problem

#1

I have Relay Shield (with 4 relays) and Wifi Shield attached to my Arduino UNO and relay uses PINS 4-7
When I upload this code to my Arduino, I get PINS triggered on and off and PIN 3 stays ON
I get my email notifications delivered but whats up with PINS?
If I run other functions, everything gets stuck. What is going on?

Here is my CODE:

#define BLYNK_PRINT Serial
#include <SPI.h>
#include <WiFi101.h>
#include <BlynkSimpleWiFiShield101.h>
#define BlueLED 3

char auth[] = "TOKEN";
char ssid[] = "SSID";
char pass[] = "PASS";

void setup()
{
  Serial.begin(9600);
  delay(5000);
  pinMode(BlueLED, OUTPUT);
  digitalWrite(BlueLED, HIGH);
  Blynk.begin(auth, ssid, pass);
  Blynk.email("user@email.com", "Subject", "My Blynk project is online.");
}

void loop()
{
}
