Cookies Misusing the Recommended “sameSite“ Attribute

Thanks for the replies and link.

@InsiteFX
I had a read of the link and set the flags in Chrome, (v 81), and the site is functioning correctly.
Additionally, I updated the config to send the cookie only if an HTTPS connection exists.

Code:

$config['cookie_secure'] = TRUE;

This fixed our site's cookies from displaying the notice.  The third-party cookies are still displaying the notice, and as @neuron says, that is not a CI issue.

Thanks again guys for your help.
