Should I remember cart contents across devices?

As an e-commerce business owner, I'm struggling with customer experience across multiple devices.

I want to understand the best practices for maintaining cart persistence, how it impacts conversion rates, and what technical strategies I can implement to create a seamless shopping experience that reduces cart abandonment and improves overall customer satisfaction.
