Call for help

This is more of call for help than a true review.

I cant get category list after I close an article.

Here is how it happens. Open a category, then tap to read an article, then close the article by tapping on the X. Now I come back to the category, but now there no left arrow on the category title bar for getting the list of categories.

Please help.
