Who do I contact if abandoned cart tracking isn't working?

I've been running my Shopify store for about 18 months now, and abandoned carts have always been a pain point. Recently, I noticed something weird—my abandoned cart tracking seems completely off. I'm seeing massive discrepancies between what my analytics are showing and what I'm actually experiencing in real-time. Some days, it looks like tracking isn't registering cart additions at all, which is terrifying because I'm spending good money on ads to drive traffic. Every missed tracking event could represent a potential lost sale. I've checked my pixel installations, verified my Shopify settings, and even consulted with my developer, but we're still stumped. The frustrating part is not knowing whether this is a technical glitch in my store, an issue with my tracking app, or something more complex happening behind the scenes. I need a clear path to diagnose and resolve this because abandoned cart recovery is crucial for my conversion strategy. Without accurate tracking, I'm essentially flying blind in my e-commerce business.
