Android: feeds don't refresh

Thanks for a great application.
Lately my feeds don’t refresh automatically : pressing a specific feed on the “all stories” screen
takes me to that feed’s screen. I see the old stories. I wait until “fetching recent stories” is done, but the screen does not refesh. I have to go back to the all stories screen and back again to the feed screen to see new stories
