It absolutely does not work well. It only just barely works if all you need is chatting in public rooms that you joined from another client (e.g. Element). Everything else (joining rooms, sending private messages to people you don't have a 1:1 room with, viewing images sent to encrypted rooms, …) is painful or impossible.

And then there's the "little" issue of it not being able to coexist with wee-slack. That's a bug Python 3.9, not in weechat-matrix, but still.

I mean, I still use it because all I really need is chatting in already joined public rooms and for that it's better than that Element/Electron crap, because it's still a weechat after all, but it absolutely is not ready for any kind of serious usage. It's just a quick hack that sort of maybe works, sometimes.
