I searched the webs and reached out to shopify support and Infinite Options with no luck yet.
When someone adds the same item (shopify variants) with different personalization in the text box (Infinite options) they get a " maximum product quantity in cart items 1 added" bubble and item won't add to the cart.
We do not track any inventory.
Shopify says it is infinite options. Infinite options says it isn't them.
Any help would be great. So many people order multiple of the same item with different names. This is a major issue.
