It runs really well now. I dropped it a few weeks ago due to some errors I was getting and the inability to see NSFW content, but that all seems to have been fixed.
Can definitely recommend. I turned on the “dark mode” and it feels quite slick.
If you’re on iOS you might want to try wefwef. I know there’s also mlemmy and mlem, but I haven’t been able to give them a try because I don’t have an iPhone.
I wonder if it has to do with the version your instance is on. We recently updated ours.
