Fox, I am using the Android client and have mark read on scrolling set. I am curious to know when you push the article status change to the server. I've seen cases where I am sure I've seen an article headline on the Android client but then later go to the Web version and the headline is still in the unread state. It is possible that in many of the cases, in the period between the use of the Android and Web client the feed and the article has been updated, but it is hard to tell. In on instance the time shown on the Web for the article would indicate that this isn't the case.
I am on beta channel of the Android client. On the server i'm using postgres and git pull daily.
