If the No Thank You button isn't showing up in the Upsell window, please follow these steps to fix it:
- From the Shopify admin, navigate to Sales channels > Online Store > Themes.
- Click the ellipsis next to your desired theme and click Edit code.
- Under Assets, select your theme's main CSS file.
Note: This varies by theme and could be something like theme.scss.liquid.
- Add this code to the bottom of the file:
#giveclosebtn{ color: black; box-shadow: 0px 0px; margin-top:-5px; cursor: pointer !important; }
- Select Save.
