Cookie consent banner / CMP overlay blocking Add to cart or checkout.

Several “cookie / consent / tracking” products can look like “shoppers cannot buy.” They do not share a fix. This page is only when a cookie consent banner or CMP overlay covers or traps clicks on Add to cart, Buy now, cart checkout, or checkout buttons. Consent banner missing, looping, or forever blocking analytics/marketing pixels (setup / preference never saves) is shopify-cookie-consent-banner-broken. Shopify admin analytics / reports not matching GA4 purchase data is shopify-analytics-not-matching-ga4. Customer events / custom pixels not firing in the Web Pixels sandbox is shopify-customer-events-pixels-broken.

Soft links when the bug is adjacent: older slug covering the same ATC/checkout overlay symptom is cookie-banner-blocking-checkout. ATC dead with no consent overlay is shopify-add-to-cart-button-not-working. Announcement bar covering UI is announcement-bar-not-showing (opposite symptom — bar missing). Upsell popup trapping clicks is shopify-upsell-popup-not-showing. This playbook stays on consent / CMP UI layer → covers or traps ATC / checkout buttons.

Reproduce on PDP and cart in a private window (pre-consent state). Attempt Add to cart and Checkout. If clicks do nothing or hit the banner, open DevTools → Elements and hover the click coordinates. Note whether a CMP root (`#onetrust`, Consentmo, Cookiebot, Shopify Customer Privacy banner, or similar) is position: fixed / sticky with a high z-index, a transparent full-screen catcher, or a tall footer covering sticky ATC / checkout.

Toggle Theme settings → App embeds for every consent / GDPR / CMP app off, hard refresh, retest ATC. Soft-check: if buttons work with the embed off, the CMP is the blocker — not theme Liquid for ATC. Soft-check: if Accept still leaves ATC dead, the overlay may remain mounted with pointer-events: auto after dismiss. Soft-check: if ATC works but analytics stay silent forever after Accept, leave this page and use shopify-cookie-consent-banner-broken. If purchase counts disagree with GA4, use shopify-analytics-not-matching-ga4. If custom pixels never fire in the sandbox, use shopify-customer-events-pixels-broken.

Pick one consent UI: native Customer Privacy banner or one CMP app — not both. Lower CMP z-index or raise ATC / checkout sticky bars so buttons stay above the banner. Disable transparent full-page catchers after dismiss. Add bottom padding to the theme so sticky ATC clears a footer CMP on mobile. If a second GDPR app embed is on, turn one off.

Retest: private window → PDP Add to cart clickable before consent (or after Accept / Necessary-only, depending on your policy) → cart Checkout clickable → Decline path does not leave a trapping overlay. Soft notes: consent preference never saving or pixels forever blocked belongs on shopify-cookie-consent-banner-broken. GA4 vs admin mismatch belongs on shopify-analytics-not-matching-ga4. Customer events sandbox bugs belong on shopify-customer-events-pixels-broken. ATC dead with no overlay belongs on shopify-add-to-cart-button-not-working.

Cookie consent banner broken / pixels forever is shopify-cookie-consent-banner-broken. Analytics not matching GA4 is shopify-analytics-not-matching-ga4. Customer events pixels broken is shopify-customer-events-pixels-broken. Older overlay slug is cookie-banner-blocking-checkout. Add-to-cart button not working (no overlay) is shopify-add-to-cart-button-not-working.

The only honest test for this page: private window → consent / CMP UI visible → click coordinates hit ATC / checkout (or fail because the CMP layer is on top) → after fix, ATC and checkout remain clickable on Accept and Decline paths without a trapping overlay. Anything else is a different product.

Stay DIY if you can spend one afternoon on the list above: prove the CMP overlay hit target, turn off a fighting consent embed, fix z-index / sticky padding, retest Accept and Decline. That is the whole playbook. No agency required. Short answers also live on the merchant FAQ.

Pay for help when the work is not the CMP CSS itself — it is connecting the stack you already have so consent / overlay / checkout exception alerts land in a channel you already check, and the live store is one workflow instead of a spreadsheet plus a Slack bot you forgot. That is the Latch AI Ops install.

What $997 USD one-time buys: lead capture on the live store, ops alerts in a channel you already check, and a checkout-ready workflow. 72 hours after collaborator access, not after payment. One live Shopify store. Access plus a delivery thread. Store URL collected at checkout. Not a SaaS seat, not a CMP consulting retainer, not a conversion guarantee, not a brand or theme job.

Other shops' public ranges, not testimonials: a checkout / ops install typically runs $500–$2,500. A full ops consulting block typically runs $2,000–$5,000. $997 is the cheap end of that work, sold as a 72-hour install of three systems — not as an earnings number or conversion-lift claim.

What it does not buy: more orders, recovered revenue, a forever CMP architecture retainer, or a case study. Latch AI Ops has not published customer proof because there are no customers yet. You are buying the install.
