When I launch the logos app, sometimes my preferred bible shows up and sometimes a book I have previously read from the library shows up. It is not always the last book I read but I book I receiently read. I am not for sure what I have done to cause this to happen. What can I do to have it have my preferred bible show up when I launch the app? Or I would be be happy if it opened the last book I had open when I close the app.
