Some customers report unable to add item to cart. I can reproduce it too(from my exp: add → remove from cart → add fail will produce the issue.).
My store: https://yexmedical.com/
Could someone please help? Thank you in advance!
Add one item to cart and add a different item to cart will also reproduce the issue.
Could someone help with this please? Many customers reporting the same issue.
Can someone help please? It is happening again.
