Quick Fix: Do Not Let Scripts Delay Payment Buttons
Accelerated checkout buttons sit under the product CTA, where every delay looks suspicious. If the product page is busy loading app widgets, tracking tags, personalization, and heavy media, payment buttons can appear late or shift after the shopper is ready to buy.
Thunder Page Speed Optimizer improves script loading and Core Web Vitals automatically. Use Thunder's feature breakdown for the automated performance layer, then use the eligibility and theme checks below.
Speed Up Checkout CTAsConfirm the Shopify Dynamic Checkout Setting
Shopify's help documentation explains that accelerated checkout buttons are controlled from the theme editor. Go to Online Store, Customize, open the product template, select the Buy buttons block, and enable the option to show accelerated checkout buttons. Repeat this for featured product sections if the issue happens on the homepage.
Use Shopify's accelerated checkout button documentation as the baseline. If the option is off, the fix is a setting. If the option is on but buttons still do not show, move to theme code and payment eligibility.
When the problem is part of a bigger product-page issue, compare it with the Shopify add to cart button guide and product page speed guide.
Understand Why Apple Pay, PayPal, and Google Pay Vary
Dynamic checkout buttons are not the same for every visitor. Apple Pay depends on Apple devices, Safari, wallet setup, and merchant eligibility. Google Pay depends on browser and account context. PayPal can show when wallet buttons do not. That is why a merchant may see PayPal on desktop but not Apple Pay, while a customer on iPhone sees a different button.
Test with real devices and payment methods instead of expecting one screenshot to prove everything. Use Safari on iPhone for Apple Pay, Chrome with a configured Google account for Google Pay, and a normal desktop session for PayPal. Then compare product page, cart page, and cart drawer behavior.
If payment buttons appear only after a long delay, read the Shopify INP fix guide and third-party script impact guide.
Check Theme Code, Cart Drawer Placement, and CSS
Shopify developer documentation says accelerated checkout buttons can be added to product templates, cart templates, sections, and cart drawers. In themes, the important piece is rendering the payment button component in a valid product form context. If a custom section removed it, moved it outside the form, or wrapped it in hidden CSS, it will not appear correctly.
In Liquid, payment buttons often appear through the product form payment button output:
{% form 'product', product %}
<input type="hidden" name="id" value="{{ product.selected_or_first_available_variant.id }}">
<button type="submit">Add to cart</button>
{{ form | payment_button }}
{% endform %} If you use a custom theme, inspect CSS for rules like display:none, opacity, absolute positioning, or z-index overlays around payment button containers. A sticky add-to-cart app or custom quick-buy block can hide the buttons without disabling them in Shopify.
For cart drawer implementations, Shopify's accelerated checkout developer docs are the better reference than random snippets.
Apps Can Hide Dynamic Checkout for Valid Reasons
Some apps intentionally suppress dynamic checkout buttons because the direct wallet path can skip a required product configuration, selling plan, bundle validation, gift option, or cart upsell. That is not always a bug. It becomes a problem when the app hides the button even for simple products that do not need special validation.
Disable subscription, bundle, preorder, personalization, and cart apps in a duplicate theme. Retest a simple product and a real configured product. If simple products recover but configured products do not, the app's checkout path is the issue. If neither recovers, inspect theme code and payment settings.

Manual Dynamic Checkout Debugging Checklist
| Check | What it proves | Fix |
|---|---|---|
| Theme setting enabled | Buttons are allowed in editor. | Enable in Buy buttons block. |
| Dawn preview works | Live theme or app is hiding buttons. | Diff product form and app embeds. |
| Only PayPal appears | Wallet context may be normal. | Test Apple Pay and Google Pay on eligible devices. |
| Buttons load late | Scripts are blocking rendering. | Reduce third-party JS and test INP. |
| Configured products fail | App validation may hide direct checkout. | Confirm subscription, bundle, or option app rules. |

FAQ
Why are Shopify dynamic checkout buttons not showing?
They may be disabled in the theme buy button block, hidden by CSS, blocked by custom product form code, unsupported for the shopper's browser or wallet, or affected by payment, bundle, subscription, or app requirements.
Why do I only see PayPal and not Apple Pay or Google Pay?
Accelerated checkout buttons are contextual. Shopify shows payment methods based on the customer's device, browser, wallet setup, currency, payment settings, and eligibility.
Can dynamic checkout buttons show in the cart drawer?
Yes, Shopify developer documentation says accelerated checkout buttons can be added to product templates, cart templates, sections, or cart drawers, but the theme must render the correct payment button component.
Can apps hide Shopify accelerated checkout buttons?
Yes. Bundle, preorder, subscription, cart, or payment-related apps can alter product forms, require cart validation, or hide accelerated buttons to prevent unsupported checkout paths.
Do dynamic checkout buttons improve conversion?
They can reduce checkout friction for eligible shoppers, but they should not replace a reliable add-to-cart and cart path. Test conversion, wallet visibility, and speed before making them the only prominent CTA.
