Since Erin Davis' article on the impact of ITP 2.1 on Adobe Analytics was posted to Medium (https://medium.com/adobetech/safari-itp-2-1-impact-on-adobe-experience-cloud-customers-9439cecb55ac), Apple has announced the upcoming ITP 2.2.
The biggest change looks to be Apple's cap of cookie persistence to one day, which is far lower than the 7 days under ITP 2.1. My understanding is that this is an attempt to go after the first-party cookies used by Facebook and Google as workarounds, but I wanted to make sure that my site's Adobe Analytics first-party cookie would still be OK (7 day cap notwithstanding). Additionally, will using something like the appendVisitorIDsTo function (appendVisitorIDsTo (Cross-Domain Tracking)) to connect visitors across different domains that I own increase the odds of Apple dropping my first-party cookie persistence to one day?
