Samesite cookies

[BernardoCF]

My site returns the following warning on the (latest) Firefox console:

Some cookies are misusing the recommended “SameSite“ attribute 3

Cookie “s_ppv” will be soon rejected because it has the “SameSite” attribute set to “None” or an invalid value, without the “secure” attribute. To know more about the “SameSite“ attribute, read https://developer.mozilla.org/docs/Web/HTTP/Headers/Set-Cookie/SameSite

However, according to this page https://experienceleague.adobe.com/docs/analytics/technotes/cookies.html?lang=en#how-do-browsers-cur...

If you have a CNAME and use the visitor ID service — your implementation will not be affected.

Well, I do have a CNAME setup. Do I really need to setup an attribute still or Adobe will handle this for me?

@BernardoCF - Take a look at the following article. It should be just a couple of quick updates to the config to add "Secure" and "SameSite=None"
