The programmers did a fix sometime back that required a somewhat long press to open a category. Too long, and the press did not work. Too short, and the press did not work. It took some time, but it was possible to learn how long to press.
OK, so they fixed that one, but you could not go back to the story list. The back feature took you back to the category list, and you had to scroll through the stories to find where you were to select the next story you wanted to read.
OK, this fix restores the capability to go back to the story list, which is now blank, until you attempt to scroll that list, at which time, you are taken back to the top of the list, once again having to scroll through the stories to find where you were.
This fix is no fix.
Through the myriad of these errors (and others) I have not commented. However, this parade of bugs tells me that the authors are not bothering to test their software before foisting it on us.
