You're redesigning Capital One's Instant Push Notifications (IPN) system, moving from multiple screens to a single view. How would you improve the user experience?

Focus on identifying the key pain points users experience with the current multiple-screen setup. Consider how consolidating information into a single view can enhance usability and accessibility. Discuss specific design elements that could improve clarity and engagement, such as intuitive navigation, prioritization of notifications, and visual hierarchy. Think about user scenarios and how different user personas might interact with the redesigned system. Finally, address any potential challenges in the transition and how you would validate your design choices through user testing or feedback.
