I just logged in on Connect for Lemmy and that is the one that shows up and down votes :) I think I had to turn that function on

So it’s pretty random whether someone sees just the sum

Also aussie.zone doesn’t always seem to fully synchronise with all the instances I visit, sometimes scores don’t load, sometimes votes from some instances don’t show so I often see everything with apparently zero votes

*Just twiddled the settings, comment score split is only shown in Connect if you turn on comment debug information, so I presume everyone on Connect is only seeing the sum
