Starting a few weeks ago, my iPhone and iPad, both with fully updated iOSs, stopped sorting by due date or priority. I often switch between the two. When I do that now, however, ToDo Cloud remains stuck in the prior view. I need to not only close the app, but also doubleclick and flip it so that it has totally quit. When it reopens it's showing the view that I asked for before I quit the app. The problem has been there for almost a month I think, and affected both my iPhone and iPad simultaneously. Please fix it - it's getting in the way of efficient use of what's otherwise a fine app.
