Is there a simplified Android User Interfaces on FireTV ?

[wireguard at rtlblus.de]

Hi,
I'm not quite sure if this is a real bug, but I only get to a simplified 
GUI on the FireTV instead of the one I'm usually used to from Andoird. 
Only when I reinstall the apk and open it right after, I get the usual 
GUI with settings options.

but i want/need the "normal" GUI (https://ibb.co/qW0BG7B) with the Split 
Option for specific apps (https://ibb.co/chCb7sY)

Thanks in advance
