I’m running the Prestige theme on Shopify and the cart has started misbehaving on mobile—both iOS and Android. Whenever a shopper adds a product, the cart grabs the previous item instead, so the cart is always one step behind. Swiping through product images or switching variations triggers a “SyntaxError: The string did not match the expected pattern,” blocking the add-to-cart action entirely. Removing items or updating quantities fails as well. Key pain points you’ll tackle: • Adding products, removing items, and changing variations must work reliably on mobile. • The cart should display the correct, current product every time. • No more SyntaxError on variant change. I haven’t modified the theme or added new apps recently, so the issue is likely buried in the existing JavaScript or AJAX cart logic. Deliverables: 1. Diagnose the underlying cause in the Prestige theme code. 2. Patch the scripts/templates so the cart functions flawlessly on both iOS and Android devices. 3. Provide a brief report outlining what was fixed and how to keep it stable after future theme updates. Please be comfortable debugging Shopify Liquid, JavaScript, and AJAX carts within the Prestige theme. A quick turnaround is appreciated so customers can check out without friction again.

Hi, I can quickly diagnose and fix the mobile cart issues in your Shopify store running the Prestige theme.

I’ve debugged similar AJAX cart and variant-selection issues across iOS and Android and can stabilize this quickly. Please share: ✔️Your store URL ✔️Access to the theme code (or collaborator access) ✔️Any console error screenshots from mobile (if available) I’ll start with: ➡️Auditing the product form, variant selectors, and AJAX cart JS ➡️Reproducing the issue on iOS and Android ➡️Fixing the variant ID binding and fetch/XHR request formatting ➡️Patching add/remove/update cart logic to ensure correct product sync ➡️Testing thoroughly across mobile breakpoints You’ll receive a fully stable mobile cart (add, remove, and update working flawlessly), complete resolution of the SyntaxError, and a concise report detailing the root cause, fixes implemented, and guidance for maintaining stability through future theme updates. I can begin immediately and prioritize a fast turnaround so your customers can check out without friction. Awaiting your response! Thanks, OOCPL
