I have two users A and B. User A created the room and invited user B to play with him. User A sends the push notification to user B's device with Room ID in it. When user B got the notification. user B will be connected to server first then user B will be joined to room ID given in notification dictionary by pressing play button. Sometimes i got an error in "-(void)onJoinRoomDone:(RoomEvent*)roomEvent" with result 4 and 5 (BAD_REQUEST and CONNECTION_ERR). It does not happen every time. It happens sometimes. I just want to make sure is this problem happening to other developers also ? Becuase it was working till yesterday.
