SameSite=None without Partitioned
A cookie is SameSite=None and Secure, but it is not Partitioned.
Why it matters
Unpartitioned cross-site cookies are what third-party tracking and some login flows rely on. Browsers keep restricting them.
What to do
Add Partitioned (CHIPS) for a third-party cookie, or stop sending it cross-site.
