Chris is deciding which of two apps to download, and he notices that a reviewer for one of them describes it as having "very poor functionality." What is MOST likely the problem that led to this comment?

(1 point)
The images it uses are unattractive
The navigation menu is confusing
The color scheme uses dated colors
The website has too few products for sale

The most likely problem that led to this comment is that the navigation menu is confusing. This would indicate that the app is difficult to use and navigate, leading to a poor user experience.
