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.
oh yeah, same. definitely felt broken to me. had to read this comment then do landscape mode and i can see the problem is the menu takes up the whole screen on mobile.
