Is there a buffer size setting in Smarters or am I looking in the wrong place?

Been digging through settings trying to find some kind of buffer adjustment option, but I’m not seeing anything obvious.

Streams play fine most of the time, but I wanted to increase buffer slightly to see if it helps with occasional stutter.
On Android TV version of Smarters.

Does this app even let you change buffer size or is that just not a thing here?
