Hello,
I know things like this were asked before on this forum. See: Advice post on Aug '21.
However, no one has answered those posts and the latest 20.0.3 docs don’t really explicitly say how to access this form.
There is documentation alluding to this being the Forcing User Profile Compliance action and turning this on with new fields does present the form on user login.
However, my question is how can we direct users to this screen when they want to update their information?
