Yep you are right, that’s it. I guess I chose the wrong instance. But this is the advantage of the fediverse. It would be nice to have some table that shows the features in each instance so that we could decide which is the right one for us. I just chose based on the direction I got from lemmy.ml.
Yeah I could log into lemmy.one on mlem and still downvote, so just removed from UI. But it was enough to make me migrate to lemmy.world.
