Regarding the new version of the NewsBlur Android app (3.5), I have it set to only show unread items. If I’m reading a feed, have read all the items in said feed, and then hit the back button, all I see is a “Loading…” screen. That’s a poor user experience. Hitting the back button again will take me to my list of feeds, but that intermittent screen just bugs me to no end.
Oh and as for the phone I’m using: Motorola Moto G, UK version, on Android 4.3.
