The Security option on the Settings Menu doesnt appeqr anymore.. What happened?

Up until very recently, I have had an option to open Security Options from teh Settings Menu. That menu item is no longer there. I have friends who can still access the security options to turn on the lobby, set a password, etc.

What happened?

Welcome to the forum!
You have “Security options” in the three-dots menu - is that what you are looking for? On which server you saw it disappearing?
