This issue is related to Chrome update where they forced to set
SameSite attribute (https://www.chromium.org/updates/same-site/incompatible-clients)
Following this link, Chrome 51 to 66 will not accept
SameSite=None. However, in Symfony settings I have set the following:
framework: ... session: ... cookie_samesite: 'none' cookie_secure: true
Now, for the Chrome client 51 to 66 I want to change
Lax, so this has to be changed on the request level I guess. The part how to detect Chrome version I know, but I am not sure how to apply
Lax after the device is detected.
I cannot change to
Lax by default because website can be iframed.
