I agree, it's an unfortunate downside. But it's still probably our best option long-term.

At least in XMPP's case, I think a way of dealing with the fragmentation is to treat Movim as the 'main' app, and to encourage any friends willing to leave Discord to just use that, and not mention other options unless you know they're a bit more tech savvy, and can understand the limitations of the other clients and just think of them as fun little bonuses (until they catch up, anyway). :)
