Can I compare abandoned cart rates across devices and browsers?

As a Shopify store owner running ads across multiple channels, I've been struggling to understand why my cart abandonment rates seem so inconsistent. Some days, mobile users drop off at an alarming rate, while other times desktop conversions tank. I'm spending thousands on Meta ads, and every percentage point of cart abandonment feels like money literally walking away from my business. I need granular insights—not just overall abandonment rates, but a breakdown that shows me exactly where and why potential customers are losing interest. Are mobile users experiencing checkout friction? Do certain browsers have compatibility issues with my store? Without precise data, I'm essentially throwing marketing budget into a black hole, hoping something sticks. I want a solution that doesn't just show me the problem, but helps me understand the underlying patterns and provides actionable strategies to recover those lost sales.
