Join session did not load the server map

If you are playing from the editor, make sure to set the play mode to “Standalone Game”. I suggest, that you go into Editor Preferences, and change a few things there as well. Set “Run Under One Process” to false, and in the Additional Launch Parameters field, type “-log”. About your issue, after you’ve joined a session, you can call UGameInstance::ClientTravelToSession. This will take care of traveling the player into the session.
