Shopify Cart Bug Fix

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.
