Definitely didn't work as I expected, but mostly just because I'm on mobile. I had to do a lot of extra clicks to do what I'd expect. HOWEVER, aside from UX it's functionally sufficient and that's more of the point, I think. But just as a suggestion to OP: in mobile, clicking a feed should take you to that feed. Currently you click a feed, there isn't any confirmation of that selection being applied, and you have to close the menu to see the feed again.
