"Ask" is the old functionality, which sends a "do not track header" that some dodgy advertisers ignore/work around. The new "prevent cross-site tracking" option is designed to work around the workarounds. It's a bit of a cat-and-mouse thing!
It should be right next to the "ask sites not to track me" option.
I actually copied that screenshot from a news article. I'm not at home right now but I'm 99% sure that I'm on 11 and that it looks the same.
I just installed Safari 11 and mine still looks like the older version without the cross site option. Does this need a "windows" style system reboot? I wouldn't think so but wanted to ask.Pretty sure it won’t be. Let me know when you check from home
