Overlay is showing on updating cart on cart page

Topic summary

A cart overlay issue is occurring where the overlay that appears when adding products to the cart is also incorrectly displaying when updating product quantities directly on the cart page.

Troubleshooting Steps:

  • GemPages initially provided CSS code to be added above the </body> tag in theme.liquid
  • The user reported this solution didn’t work and also affected the checkout page
  • GemPages then provided updated code with modified instructions

Current Status:

  • The issue remains unresolved
  • The latest recommendation involves adding revised code to theme.liquid above the </body> tag, specifically avoiding placement in header.liquid or checkout pages
  • Awaiting confirmation on whether the updated solution resolves the overlay problem

When adding a product to the cart, the cart drawer opens and an overlay applies on the page but also affects the cart page when I increase or decrease the product on the cart page.
