Also I can see two dms from you, but in my dms section, swiping to reply (as works on Thunder to reply in any other part of the UI) does not work.
Going to your profile page yields no buttons to reply.
Maybe I have to do some kind of ... adding of lemmy.world, somewhere in the UI, as I'm from .zip, and dms follow some kind of different protocol than commenting on posts?
???
Or maybe I'll try Odyssey and its less borked?
Edit: Sync, not Odyssey, getting my FOSS apps mixed up.
Maybe you could try to restart your client. On Sync go to your inbox, click on the triangle pointing down, and a menu will open, you can switch categories there, as it doesn't show DMs by default.
