Problems discovered after most recent update

The latest app iOS 9 update seems to be defective. Im encountering problems and bugs such as, when I enter a word into the search field, it just remains there, no matter how many other words are researched. Using the back arrow keys does nothing to remove the entry. Additionally, after looking at verb conjugations, it is impossible to back out to the original screen. These "issues" need immediate attention and resolution.
