Does the host now need to join as well?

I have some code Utilizing NGO transport and relay. I followed along the demos by Dilmer Valecillos (https://www.youtube.com/playlist?list=PLQMQNmwN3FvyyeI1-bDcBPmZiSaDMbFTi). I was having some timeout issues so I updated my packages. Now, the when the host starts, it never connects as a client.

Code (CSharp):

1.  
2.  
3. public async void StartCreateGame()
4. {
5. // sign in, create allocation, set transport's relayServerData, and get the join code
6.     await RelayManager.Instance.SetupRelay();
7.  
8.     if (NetworkManager.Singleton.StartHost())
9.     {
10.         Debug.Log("Host started..."); // I see this message
11.     }
12.     else
13.     {
14.         Debug.Log("Unable to start host...");
15.     }
16.     joinCode = RelayManager.Instance.HostData.JoinCode;
17.    
18. }
19.  

In another script (MultiplayerPlayersManager), I have the OnClientConnectedCallback:

Code (CSharp):

1.  NetworkManager.Singleton.OnClientConnectedCallback += (id) =>
2.             {
3.                 Debug.Log("Client connected Callback"); // Never fires for the host
4.                 if (IsServer)
5.                     playersInGame.Value++;
6.  
7.                 // playerIdsInGame.Add(id);
8.                 Debug.Log($"players in game: {playersInGame.Value}"); // Host sees "1" after the other device joins, the other device sees 0
9.  
10.                 // AnswerData.Add(new MultiplayerGameData(id));
11.                 // UpdateMultiplayerClientIdCache();
12.  
13.                 if (playersInGame.Value == RelayManager.DefaultNumberOfMaxPlayers) //2 players max
14.                 {
15.                     // todo: check client versions first
16.                     // SetOtherPlayerId();
17.                     if (!IsSpawned)
18.                     {
19.                         Debug.LogError("not spawned");
20.                     }
21.  
22.                     // send signal
23.                     SendPregameSignalClientRpc();
24.                 }
25.             };
26.  

Has Relay, NGO, or Transport changed how the host is supposed to connect?
