After uninstalling the GoKwik app, the Buy Now (direct-to-checkout) button vanished from every product page. Nothing else in my theme was intentionally modified, so the required Liquid snippet is either missing or disabled. I need that button reinstated on all product pages, keeping the exact colour, size, font and hover state it had before. Functionally it must still skip the cart and open the native Shopify checkout. Here’s what the finished job should cover: • Inject the Buy Now code back into the product form of the active theme • Apply the previous styling so the storefront looks unchanged • Verify desktop- and mobile-view behaviour and confirm the one-click flow works A clean solution in Shopify Liquid, HTML/CSS (plus JavaScript only if essential) is all I’m after—no new apps or design tweaks. I’ll provide theme access right away so you can start as soon as you accept.
