Does Apple Safari Intelligent Tracking Prevention Impact Einstein Recommendations?

Yes. Apple's Intelligent Tracking Prevention is a WebKit feature that reduces cross-site tracking by limiting cookies and other website data. This feature works for Safari web browser users. Due to the limited nature in which the Einstein Recommendation platform uses cookies, Einstein Recommendations work as designed for Safari users. Some users have reported that they must disable Safari's cross-site tracking feature to see the recommendations. If the recommendations aren’t appearing on your main page, try enabling Safari’s Prevent cross-site tracking setting. The cross-tracking option is enabled by default.
