Same-site flags were removed in Chromium 91 - How can I disable them for local development?
there is an temporary solution for this problemset an commond line in chrome/edge (v91) launch cofing like this:
Windows：open Chrome/edge shortcut's property，add: "--disable-features=SameSiteByDefaultCookies" after Target property
in my pc,it like ** "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --disable-features=SameSiteByDefaultCookies ** finally
then restart your chrome/edge,try again
Starting from Chrome 91 these flags are not needed since it is now a default behavior. It means either this feature(s) must be configurable in settings or non-configurable at all (and this is our case!).
However, there are still similar launch feature flags available up until Chrome 94:
SameSiteByDefaultCookiesCookiesWithoutSameSiteMustBeSecure
For example, launch command in Linux then would be
google-chrome --disable-features=SameSiteByDefaultCookies,CookiesWithoutSameSiteMustBeSecureI guess after Chrome 94 one has to just deal with it
For the local development in chrome 91, we need to edit the cookie SameSite attribute and set it as None.
