Describe the bug:
If one of the users restarted the app during a call and reconnected to the room he can see others, but his video does not appear on remote sides anymore (onPublishersReceived called, but onRemoteStreamReceived doesn't).

Steps to Reproduce:

1. connect to video conf
2. restart the app
3. reconnect to the video conf

Logs:
https://gist.github.com/tw1st88/3e196bf0fd623affb81dfa02970955f5

Actual result:
Video of the reconnected user doesn't appear anymore on remote sides.

Expected behavior:
Video of the reconnected user reappears for all participants.

Additional info
I'm on the free plan. In my case I don't need accept/reject call UX, just connect/disconnect video room.
Code that I use
sign up screen:

await createSession();
final cubeUser = CubeUser(
  login: nickname,
  password: '00000000',
);
await signUp(cubeUser);

call screen:

ConferenceConfig.instance.url = SERVER_ENDPOINT;

final cubeUser = CubeUser(
  login: nickname,
  password: '00000000',
);

if (!CubeSessionManager.instance.isActiveSessionValid()) await createSession(cubeUser);
final user = await signIn(cubeUser);  // from connectycube_core.dart
_callClient = ConferenceClient.instance;
_callSession = await _callClient.createCallSession(user.id);

RTCMediaConfig mediaConfig = RTCMediaConfig.instance;
mediaConfig.minHeight = 180; 
mediaConfig.minWidth = 180;  
mediaConfig.minFrameRate = 15; 

_addEventHandlers(_callSession); // same as in example
_callSession.setSessionCallbacksListener(this);  // as in example, but commented _closeSessionIfLast() for reconnection testing

_callSession.joinDialog(widget.roomId, ((publishers) {
}));

Hello @tw1st88, sorry for the late answer. Please, check on the opponents' side, did they subscribe to the user again after its reconnect. Can you reproduce the same issue in our sample?

Hello, @TatankaConCube.
I checked this. The user subscribes again after his opponent reconnected.
And I can reproduce the issue in your sample with small adaptations. Here is the code https://github.com/tw1st88/connectycube-flutter-samples
