Users already in a voice channel are not shown after reopening the app

I don't think it is a bug, whenever I join on another instance, I get this pop up

You're right, that's my bad! This is actually tied to #232 then. If you have both instances open at the same time BEFORE joining a voice channel, it properly displays this pop-up. However, if you open Fluxer from another device after having joined the channel from the initial, your first session is not displayed and this pop-up doesn't trigger.
