Unless you have your feeds arranged in a folder, the Android app does not display the individual feeds, giving you only the option of viewing all items.
I fixed this by (manually, ugh) moving all of my feeds to a folder, but I would like to see this fixed.
The fix for this is hopefully going out later today. I have the commit in my inbox and I just need to test it.
And I just manually moved all the feeds, argh! 
That’s good news. Is there a way to do mass moves of feeds to different folders?
Not yet, but I am planning to build an organizer as one of my top 5 priorities post-redesign.
Sweet. Looking forward to it.
