Matrix is nice, but it’s still very bad UX wise.

I’ve used it on and off for years now, and about 2-4 times a month it loses my chat view encryption keys, and loses me my entire chat history. It also regularly has sync issues between devices signed into the same account, and is relatively slow sometimes to send messages.

Of course, that’s just my anecdotal experience, but I’ve tried many messaging platforms over the years, and while Matrix (and multiple of its clients, primarily Element) is the most feature-complete compared to Discord, it’s nowhere near properly usable long-term for a mass-market audience.
