I have found a bug in the Android app (which I love!). If you flip between the “unread” and “focus” duplicate items start to appear for shared items and to a lesser extent normal feeds. It seems like it mat be something to do with the folders collapsing/expanding.
Spoke too soon. Some updates it’s clean, some updates you get some folders duplicated. It seems it is capable of fixing itself on a subsequent refresh but the problem will return an indeterminate number of refreshes later.
This is occurring to me as well (admittedly, unpaid (as yet) account) with version 1.0.55 on Android 4.2.2 (stock, Galaxy Nexus), as well as a Android 4.2.2 Nexus 7.
A bit perplexing and frustrating, and when I import my full swath of feeds likely to become more so…
It’s very likely that this isue will get fixed in the next “big” android update that will address the general slowness of the app. The duplication bug is a side effect of some of the same root causes.
It seems this is taken care of with the latest update (version 1.2). I haven’t seen it on my phone (Motorola Razr Maxx HD on 4.1.2) or my tablet (Samsung Galaxy Tab 2 on 4.1.?, not sure of the version on that one). App seems pretty snappy most of the time. I have seen a few oddities in marking feeds as read but that is fairly infrequent.
