You're not wrong lol though tbf 0.18.0 made Lemmy quite a bit more usable for me.
I hope they will add e2e encrypted DMs
I don't think that's possible to do using activity pub, but if you have a matrix account you can add it in your settings. When viewing the profile of someone who has a matrix account set on the web ui, there will be a button that says "send encrypted message". You should see it if you look at my profile page, for example.
The Memmy dev has pushed almost 70 major TestFlight builds in two weeks. Dude is a machine.
