Only been using the app a short time but definitely like the new look so far.
First thing I noticed was that after installing the app I had no "reply" button to respond to posts. Turns out I wasn't logged in. So I opened the settings and added my username and password. I get an error with a failed username/password but no confirmation when I have the correct one.
Anyway the bug I see is that even though I'm logged in the menu still displays that I am "Logged out" which can't be the case since I'm posting this from the app.
