Customers can't add to cart

Shopify Discussion
,

Topic summary

Customers report that clicking “Add to cart” glitches and leaves the cart empty, preventing checkout.

  • Another merchant notes the same behavior on two stores (u brands.com and smead.com), implying it may affect multiple shops.
  • Support requested the affected store’s URL and tested the original reporter’s site; on their end, add-to-cart worked as expected and the cart populated correctly.
  • Based on this, support believes the problem is likely local to the customer’s device or browser and advised trying a different browser or device.

Outcome and status:

  • No platform-wide issue has been confirmed.
  • The original store appears functional from support’s testing, but affected customers still need to try the recommended local troubleshooting.
  • The additional merchant’s stores have not yet received a specific diagnosis; issue remains partially unresolved and open pending further feedback.

People can’t check out on my site because whenever they hit the add to cart it glitches and shows nothing in the cart

Hi, @swiftkatana .

Thank you for sharing that.

I just tested it on my end and its working as it should. That ususally means it is a local issue with the customer. I recommend asking them to try a different browser or device.
