Why can customers only purchase one item at a time in my store?

Hello does anyone possibly know why my store only allows my customers to purchase one item instead of multiple items??? Please help me asap

Hi there @AllOutGrind1 .

This sounds like it could be an error with how your current shipping rates are set up, it is hard to say for sure without investigation though Can you show me a video example of the error? Can you please share with me a link to your storefront?

When did this problem first begin? Does it coincide with you editing anything on your store? Changing shipping settings, or adding/removing apps perhaps?
