If there’s an issue with the personalization feature in your car rental app, here are key areas to check:

Data Collection and Accuracy: Ensure that the app is properly capturing user preferences, rental history, and other relevant data. Missing or incorrect data can affect recommendations.

Recommendation Engine: The algorithm may need fine-tuning to ensure it’s delivering the right suggestions based on user behavior, location, or car preferences.

User Interface (UI): Review the UI for clarity and ease of use. Personalized content should be accessible and easy to interact with.

Backend Performance: Slow load times or server errors could hinder real-time personalization.

Optimizing these aspects can resolve the issue and enhance the user experience.
