Turnkey now checks for filled SysSingleton properties if found (in StreamingApp_API_Base Open). We strongly suggest you have these as non-persistent to get the desired per-user-session result:

• SysSingleton.ClientIp:String?, Transient - if found, Turnkey will fill it in with ClientIp.
• SysSingleton.SystemType:String?, Transient - if found, Turnkey will fill it in with TurnkeyNetFramework or TurnkeyNetCore.
• SysSingleton.UserAgent:String?, Transient - if found, Turnkey will fill it in with the User-agent from the client.
• From 2023-10-17, we call a method OnCurrentUserChanged if found on SysSingleton whenever the CurrentUser is set or nulled out. This happens when a user logs in or out. For MVC, it happens on postback.
