Does "I read it" mean no cookies are set?
You will no longer be getting GA scripts added to the page, the cookies are still there, good point, I can see if we can delete them for existing users
So if I dismiss ("got it"), does that remove ALL cookies? e.g. persistent login?
No cookie deleting at the moment, good point.
Persistent login is considered "essential" cookies and AFAIK we don't need consent for that.
