Chartboost Ad not showing in Device

So i have been having trouble with t$$anonymous$$s for 2 days straight and im wondering why my ads do not appear when i test on my android device. I followed everyt$$anonymous$$ng from the Documentation, started a campaign after i added my app and also enable test mode. Here is 2 Seperate scripts one has everyt$$anonymous$$ng from the documentation and the other shows the interstitial in my main menu script

Chartboost Script

 using UnityEngine;
 using System.Collections;
 using Chartboost;
 
 public class Chart : MonoBehaviour {
 
     void OnEnable() {
         // Initialize the Chartboost plugin
         
         // Replace these with your own Android app ID and signature from the Chartboost web portal
         CBBinding.init("Device ID", "Device Sig");
     }
     
     
     void OnApplicationPause(bool paused) {
         // Manage Chartboost plugin lifecycle
         CBBinding.pause(paused);
     }
     
     void OnDisable() {
         // Shut down the Chartboost plugin
         CBBinding.destroy();
     }
     
     
     
     public void Update() {
         if (Input.GetKeyUp(KeyCode.Escape)) {
             if (CBBinding.onBackPressed())
                 return;
             else
                 Application.Quit();
         }
     }
 
 }

Menu script that calls CBBinding.int

 using UnityEngine;
 using System.Collections;
 using Chartboost;
 
 public class Menu2 : MonoBehaviour {
 
 
         private Ray ray;
         private RaycastHit rayCastHit;
 
 
         void Update ()
         {
             
             if(Input.GetMouseButtonDown(0))
             {
                 ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 
                 if(Physics.Raycast(ray, out rayCastHit))
                 {
                     if (rayCastHit.transform.name == "PlayButton")
                     {
                         Application.LoadLevel("Main Game");
                     }
                 }
             }
         }
 
     void Awake() {
         CBBinding.showInterstitial(null);
     }
 
     }

Also: My Device ID and Sig is there soooo just for an FYI. If you could help thank you
