Hey,
Thanks for sharing the details I understand how important this is, especially with your launch coming up.
What you’re describing (the “Place Order” button briefly disappearing and reappearing) is usually caused by a JavaScript re-render or cart validation script triggering when the page loads or updates. This often happens with cart drawers, dynamic sections, or apps that modify the checkout/cart behavior.
A few quick things I’d like to check to pinpoint it properly:
– Which theme are you using?
– Have you recently added any cart/upsell/discount apps?
– Does the issue happen consistently or only on first load?
Yes, please go ahead and send over your main-cart-footer.liquid file that will help a lot. I’ll review it and show you exactly what’s causing the flicker and how to fix it cleanly.
We’ll get this sorted so your store looks polished before launch
