I’m seeing something similar to this in the latest IOS version. I haven’t spent a lot of time trying to determine sequence to reproduce (I’ll try to pay attention), but it has happened several times. My app will get into a state where I can select a story on the left, but the view on the right will not change. it will change to read in that view, but when I go back to the main screen of the app, it will be there with all the others as not read. I can’t read stories until I kill the app and load again.
