Key Learnings
- Immediate access to cart actions didn't significantly increase add-to-cart rates.
- The change slightly boosted engagement but didn't convert into higher sales.
- Simplifying the add-to-cart process did not overcome the need for detailed product exploration.
- User behavior still favors in-depth product review before purchase.
