When matchmaking is successful on the client, the client has no easy method to obtain the Server ID.
The Server ID is required when looking for the server logs in the Game Manager, essential for tasks such as QA.
Currently, the only way to obtain the Server ID is to use in game networking to distribute the Server ID to the clients or via user read only data. Would be simpler and faster if the Server ID was returned in the API calls to GetMatchmakingTicket and/or GetMatch.
