Hi! I am using the Supply theme for my shopify store: https://kisseduapparel.com/. On a mobile device, customers are not able to add more than one different product to the cart, but are able to add multiple of the same product. If the customer adds a second item to the cart, it kicks out and replaces the original first item. This issue only applies to the mobile site, on the desktop site customers can add as many items as they want.
How can I fix this issue?
Thanks
