Even though Feb 8 version claims improvements, scrolling is jumpy, often delayed by several seconds making it difficult to read. Often page scrolls so fast over many paragraphs it cannot be stopped by tapping on screen. This requires scrolling back up page & hunting for place I left off reading. Also, large screen-length ads/promos & article related photos/graphics appear to either cause or contribute to scrolling problems. App still needs a lot of under-the-hood work.
