I'm trying wrap my head around ITP2.0 and what this will mean for my first party cookies.
Adobe have this whitepaper but not since found anything on 2.0 and it's impact:
Adobe Analytics and ITP
If there is anything useful on 2.0 that is out there please let me know.
The KB article that you linked has since been updated with details for ITP 2.0. Feel free to follow up with any questions that the KB article doesn't cover. Thanks!
