The mobile app is still based on a (very) old Teamspeak version. Good for voice chat, unusable for everything else.
Screensharing also works via P2P in a “screenshare” chat. That way you can already use it while being on selfhosted servers. Complete selfhosted support will be added in later updates though.
But yeah, there are indeed no text only rooms.
Hey. I gave my LED version with the Elec Sticks to a friend of mine, as I bought myself an OLED one.
I really liked them though, as there is almost a 0 deadzone and (more importantly) a round deadzone.
My friend also likes them, as he didn’t want me to switch them back to the OEM ones.
