I haven't been able to comment on a HN submission from a mobile device in god knows how long. I've tried so many apps. not having an orange look just feels odd, but more to the point I constantly find either the apps are great for consumption but not commenting, or the other way aroubd. This app seems to be no exception. The news:yc app was my favourite client until commenting broke. Haven't had a response from the developer since. I'm now using Hakka News but "no orange" is very strange.
