We have a similar issue with an ordering system on campus, not SciQuest, but I can tell you that they are of course lying. A SameSite issue with an app has nothing to do with the SAML (or OIDC or....) IdP at all and can't possibly be fixed by it. The issue is with the app(s). They have to adjust their cookies (or people just can't use Chrome).

This ordering use case is a prime example of the SameSite problem. You're mid-session so the 2 minute rule Chrome implemented doesn't help and suddenly the change that "didn't break anything" is now fatal.

With Chrome's change finally rolling out, I would imagine the screaming is imminent.

I am not aware of any other browsers starting to implement this idiotic change, though the assumption is they will.
