2 days late, but creator here -- this is as designed.
Every entry on hckrnews has hit the homepage, so 'all' is exactly that. The current homepage filter is simply a filter to show what is presently on the homepage of news.ycombinator.com.
But this is not the first time someone has been confused about the homepage filter, so I could probably explain that better somehow.
This matches my experience having received one Nov 2018 (and returning it a few weeks later). It was constantly getting my actual sleep times wrong, more often than not marking me as being asleep while watching tv in the evening.
After contacting support, their solution was an upcoming update to their app where I'd be able to edit the data so that I could override the app whenever I knew it was wrong. Which completely invalidates the primary reason to own this product. I mean, if I knew when I was asleep, why would I need a ring to track it?!
So given that it couldn't properly track sleep, doesn't track activity (by design), the only other purpose in my mind was to track HRV. And count me as skeptical of the accuracy of that data as well.
"Water, Pea Protein Isolate*, Expeller-Pressed Canola Oil, Refined Coconut Oil, Rice Protein, Natural Flavors, Cocoa Butter, Mung Bean Protein, Methylcellulose, Potato Starch, Apple Extract, Salt, Potassium Chloride, Vinegar, Lemon Juice Concentrate, Sunflower Lecithin, Pomegranate Fruit Powder, Beet Juice Extract (for color)" vs "Beef" is a minuscule difference?
Plant based meat is "Improving Human Health", vs Animal based meat which according to them has "16% Increased cancer risk", and "21% Increased Heart Disease Risk.
