Three developers and still no fix — that's genuinely frustrating, especially when you can see the drop-offs happening in real time. Checkout abandonment at the payment step usually comes down to one of three things: a broken redirect, a trust signal missing, or a Liquid snippet conflict. I've seen this exact pattern before and it's almost always fixable within a day once the root cause is found. I'll audit your theme first, show you exactly what's breaking, then fix it — no guesswork. Would it be okay if I asked one quick question about your current payment gateway before we start?
