Thumbs up on mobile (web) doesn't work
You Complaint
It's not a big issue, but if an answer is great, why not give positive feedback? It works on the desktop layout (even on mobile), but with the mobile viewport, it's broken - or at least doesn't give clear feedback to the user. How about just checking the thumbs-up like on desktop and then closing the menu? It's a very minor thing, but still an annoying UX failure.
