I'm using Android App version 1.0.23 on a HTC Velocity 4G running Android 4.0.3.
Consistently, when I navigate to a question from the sidebar, the Android app will load up an old version of the question list, and I'll have to refresh it to see the updated question. I'll try to illustrate:
The question list, after refreshing:
Recent questions! Perfect. If I visit a question then hit back to return to this view, I'll see these same questions. Great!
But if I choose to navigate to this page through selecting the sidebar... it'll load up the following set of questions, which are two days old. Please be aware I am scrolled to the top; I have not scrolled down at all.
If I refresh, I'll see the new questions again as I should. But next time I navigate back to this site via the sidebar, I'll see these old questions again.
This behaviour is consistent for visiting other sites via the sidebar.
