Remote Config doesn't work on devices

Hey,

I'm using unity 2020.3.12f1
I'm trying Remote Config for the first time. I added Setting, Campaign and made my script and everything working just fine on unity editor. but on devices nothing had changed at all !!!
here is my script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Unity.RemoteConfig;
5.  
6. public class EidAdhaManager : MonoBehaviour
7. {
8.     public struct userAttributes { }
9.     public struct appAttributes { }
10.  
11.     public bool isEidAdha = false;
12.  
13.     public GameObject eidAdhaEvent;
14.  
15.     public GameObject eidAdhaBackground;
16.     public GameObject defaultBackground;
17.  
18.     public GameObject eidAdhaSlidePuzzleText;
19.     public GameObject defaultSlidePuzzleText;
20.  
21.     private void Awake()
22.     {
23.         ConfigManager.FetchCompleted += ApplyRemoteSettings;
24.         ConfigManager.FetchConfigs<userAttributes, appAttributes>(new userAttributes(), new appAttributes());
25.     }
26.  
27.     void ApplyRemoteSettings(ConfigResponse response)
28.     {
29.         isEidAdha = ConfigManager.appConfig.GetBool("isEidAdha");
30.  
31.         if (isEidAdha == true)
32.         {
33.             SetupEidAdha();
34.         }
35.         else
36.         {
37.             SetupDefault();
38.         }
39.            
40.     }
41.  
42.     void SetupEidAdha()
43.     {
44.         eidAdhaEvent.SetActive(true);
45.  
46.         eidAdhaBackground.SetActive(true);
47.         defaultBackground.SetActive(false);
48.  
49.         eidAdhaSlidePuzzleText.SetActive(true);
50.         defaultSlidePuzzleText.SetActive(false);
51.     }
52.  
53.     void SetupDefault()
54.     {
55.         eidAdhaEvent.SetActive(false);
56.  
57.         eidAdhaBackground.SetActive(false);
58.         defaultBackground.SetActive(true);
59.  
60.         eidAdhaSlidePuzzleText.SetActive(false);
61.         defaultSlidePuzzleText.SetActive(true);
62.     }
63.  
64.     void OnDestroy()
65.     {
66.         ConfigManager.FetchCompleted -= ApplyRemoteSettings;
67.     }
68. }
69.  

any idea what's wrong???

 

Solved...
seems that I should publish a release first (or Testing release) to save Remote Config updates on it.
so it doesn't work on any previous releases.

 

Oh! I have to release my app to App Store too?
because I testing it on xCode and it not get any value from remote config
it just "" a black value.
