This may or may not be a related problem, but Lemmy does not show accurate sub counts for communities outside of this particular instance (i.e. ones made on lemmy.ml, lemmy.world, etc.). I checked beehaw.org, and the same problem occurs there. However, upvote counts and comments seem to be the same across instances (when not taking defederization into account).
Ionic is the perfect mix of embellishment and practicality.
