The font size in Jerboa is way too big right now, it's not a good experience. There's an issue on their GitHub and apparently this is a bug in their markdown parser. I'll give it another shot once they fix that, but for now, I just use my instance from a mobile browser and it's not half bad. "Reddit bad" memes aside, Lemmy's mobile UI is actually pretty good... unlike Reddit's.
I've decreased the don't size on step, which makes comments just a bit too large, and other text a bit too small 😄 I am not complaining though, it's totally fine
