I've been trying it out with a group of people. (On Linux and Android)

It's pretty bad still. The concept is solid but each client and server has their own way to go about things. Most are missing desired features like calling and screen sharing. Some even lack group chat...

Reactions and custom emojis are sent through an unencrypted side channel. Rich formatting such as code blocks are inconsistent across clients.

You're pretty much stuck using the mainline client element to get the best discord lite experience. But it's still pretty junk at hq screen sharing and group calls. It's missing audio capture and a decent audio filter essentially.
