Your ads run, but Meta can't see the sales? Classic picture: pixel installed but events missing, Purchase lost or doubled, campaigns optimizing for visits instead of purchases. I fix that: full funnel events (ViewContent, AddToCart, InitiateCheckout, Purchase), browser and server via Conversions API, deduplicated by event_id, verified live in your Events Manager with before/after screenshots. Free diagnosis first, you see what's broken before you pay anything. The fix usually takes a day or two, on your platform, no migration. I run my own production store and just closed this exact bug on it: a silent loss of server-side Purchase events.
