Should I track cart abandonment differently for mobile vs desktop?

As a Shopify store owner running ads across multiple channels, I've noticed something peculiar: my mobile cart abandonment rates are significantly higher than desktop. It's driving me crazy! I'm spending good money on Meta ads, driving traffic that looks promising, but then these potential customers just... vanish. My mobile conversion rate hovers around 1.2%, while desktop sits comfortably at 3.5%. I know mobile shopping behavior is different—smaller screens, more distractions, potentially slower load times—but I can't just accept these numbers. Every abandoned cart feels like money literally slipping through my fingers. I've tried generic pop-ups and generic discount strategies, but nothing seems to move the needle. The real frustration is knowing these are warm leads—they've already shown interest by adding products to their cart. Something is breaking in that critical mobile conversion moment, and I need a systematic, data-driven approach to understand and fix it. I'm not just looking for a band-aid solution; I want to truly understand the nuanced differences in mobile vs desktop shopping behavior and create a targeted strategy that respects both user experience and my bottom line.
