Question Error on SignInAnonymouslyAsync

Hello,
i'm using the following code to initialize remote config :

Code (CSharp):

1. private static async Task InitializeRemoteConfigAsync()
2.     {
3.         if (UnityServices.State == ServicesInitializationState.Uninitialized)
4.         {
5.  
6.             try
7.             {
8.                 await UnityServices.InitializeAsync();
9.             }
10.             catch (Exception ex)
11.             {
12.                 Debug.LogError("Unity service autentication faled in InitializeRemoteConfigAsync methos. Error " + ex.Message);
13.             }
14.             // initialize handlers for unity game services
15.            
16.         }
17.  
18.         // options can be passed in the initializer, e.g if you want to set analytics-user-id or an environment-name use the lines from below:
19.         // var options = new InitializationOptions()
20.         //   .SetOption("com.unity.services.core.analytics-user-id", "my-user-id-1234")
21.         //   .SetOption("com.unity.services.core.environment-name", "production");
22.         // await UnityServices.InitializeAsync(options);
23.  
24.         // remote config requires authentication for managing environment information
25.         if (!AuthenticationService.Instance.IsSignedIn)
26.         {
27.  
28.             try
29.             {
30.                 await AuthenticationService.Instance.SignInAnonymouslyAsync();
31.             }
32.             catch (Exception ex)
33.             {
34.                 Debug.LogError("SignInAnonymouslyAsync in InitializeRemoteConfigAsync methos. Error " + ex.Message);
35.             }
36.  
37.         }
38.     }

Everything works fine on the Editor, I'm also able to retrieve the data from the remote Config backend, the problem is when I built on the device where I get the error that you can find attached, What I'm doing wrong?

 

I solved, here: https://forum.unity.com/threads/sig...ror-using-remote-config.1324428/#post-8373504 you can have a look at the solution.
Thanks anyway
