--- Comment #41 from Deniss Kozlovs <deniss at codeart.lv> ---
The problem is, "None" should not be treated as "Strict" because they have opposite meanings. "Strict" means that cookie will not be transferred to third-party, and not be transferred back when returning from third-party domain.
"None" means default behavior that existed since 1997.

This now requires a dirty hack (by using regex to parse user agent) to be made when setting session parameters in the backend, because Chrome now requires SameSite=None when using cross-domain redirects back and forth (for example, making payments).
