Does Safari tracking protection work?

Yesterday I was using Safari to browse three specific products on a web shop. Safari Tracking protection is enabled on both mobile and Macbook. I am not logged on Facebook from Safari.

Today my Facebook feed serves an ad from ad.doubleclick.net, containing identically those three products I browsed yesterday.

I am logging in on Facebook from a Chrome browser only. I am using PrivacyBadger on my Chrome and Firefox browsers. I am not logged in on Google from Safari on neither Mac or iphone.

I am tempted to conclude that Safari tracking protection does not work. Or is there something I have missed?
