I tried looking through the support but did not find an exact answer in regards to forms being hosted on company site, i.e. not a Marketo landing page.
I am using Chrome Canary 81.0.4020.0 and see the warning message:
A cookie associated with a cross-site resource at <URL> was set without the `SameSite` attribute. It has been blocked, as Chrome now only delivers cookies with cross-site requests if they are set with `SameSite=None` and `Secure`.
The actual error that is concerning is attached below and appears to be an authentication error for forms2.min.js
Everything is working as intended on FF, Safari, and Chrome 79.0.3945.88 and so I just want to be prepared if this issue is associated with cookies or something more serious.
