When scrolling through Saved Stories on the Android app, newly loaded stories get sorted into apparently random positions in the story list. This causes items to shift up and down with no apparent logic. Some newly loaded items will even sort above the currently viewed stories, pushing later items down. This makes it practically impossible to review Saved Stories in the Android app.
This started happening perhaps two months ago. Sorry for the late bug report, I kind of assumed it was a known issue and would be fixed soon.
