handling 2 Netcode For GameObjects NetworkManagers in one scene

[navidhaghighi]

Hello
We have 2 NetworkManager components , 1 for a lobby and 1 for voice chat.
we use Netcode for gameobjects integration.
It works completely fine on editor but doesn't work on android , what is the different between Editor and android?
After we connect to Dissonance server ,DissonanceSetup Doesn't show connected players anymore.
We have tested our network with only one NetworkManager and it works correctly.
before we use the second NetworkManager and instantiate DissonanceSetup object we shutdown the first networkmanager like this:

foreach (var networkObject in VoiceLobbyClientManager.Instance.GetComponent<NetworkManager>().SpawnManager.SpawnedObjectsList)
{
    if (networkObject != null)
    {
        Destroy(networkObject.gameObject);
    }
}

VoiceLobbyClientManager.Instance.GetComponent<UNetTransport>().DisconnectLocalClient();
VoiceLobbyClientManager.Instance.GetComponent<UNetTransport>().Shutdown();
VoiceLobbyClientManager.Instance.GetComponent<NetworkManager>().Shutdown();

Unity version : 2021.3.39f
Dissonance version : 9.0.4
Netcode for gameobject version : 1.9.1

Dissonance internally uses NetworkManager.Singleton to get the NetworkManager. If you have two it's likely that Dissonance is trying to use the wrong one, causing the failure on Android.

You might be able to make this work by delaying the startup of Dissonance. If it's in the scene, but disabled, it won't try to access the network manager. You can then do your shutdown, wait until the new one has started and then enable the Dissonance gameObject.
