Ok that clears a lot. And, as almost always, Discourse team has already identified the issue and work is on the way. But in the mean time,
Can’t this (i.e. what I’ve raised) be solved by simply replacing 2 words:
From: " engagement from the visitors, who are not currently signed in"
To: "engagement from signed-in users, signed in users who wish to remain ‘anonymous’
Or does it create confusion in some other way?
