I have been experiencing this too. I thought it was just an error but now 2 of my stores have that big check mark. I even tried to open it on different browsers and devices. Still the same.
Topic summary
Users report a large black checkmark appearing briefly on their Shopify stores before content loads, primarily affecting sites using the Dawn theme (versions 2.0-15.2.0) and Studio theme.
Root Cause:
The issue stems from improper code placement in the cart-notification.liquid file. The style tag loads after the HTML element renders, causing the unstyled checkmark icon to display momentarily.
Primary Solution (Most Effective):
- Navigate to Themes > Edit Code > Snippets > cart-notification.liquid
- Locate the
<style>tag within the file - Move it to appear directly above the
<cart-notification>element (instead of after the liquid block) - This ensures styles load before the element renders
Alternative Workaround:
- Search for
icon-checkmark.liquidin theme code - Comment out the entire file using HTML comment tags (
<!--and-->) - Note: This disables the icon entirely but may affect dependencies
Status:
Multiple users confirmed the code relocation fix works successfully. The issue persists across Dawn theme versions as of 2025, with no official Shopify resolution announced. The problem appears related to a structural flaw in the theme’s default code rather than user modifications.
