It’s interesting to visit threads from an mbin instance because it shows you the number of up votes and down votes. When I see a Lemmy thread with 10 up votes then I go over to visit the same thread from mbin and see 20 up votes and 10 down votes, it really gives a different perspective.
The only relevant user setting I have is “show scores”. False shows no scores at all for comments and threads. True shows up votes and down votes on comments, but not threads. So if lemm.ee shows you up and down votes on threads and you are using the web client, then that must be a server-side option or mod. It could be a client capability but I’ve not found a worthy 3rd party client for Lemmy yet (for the desktop).
I'm using Voyager on Android and desktop, and I can see the upvotes and downvotes. At the moment your post has one of each, and the comment that I'm replying to has one upvote and no downvotes.
You can try it at vger.app on the desktop 👍
That confirms it then: it’s a client feature. I also have a dbzer0 acct as you do, but I only see the total, which apparently can be attributed to the stock web client.
