I'm struggling with Cart history trouble.
I made simple unity app that open own shopify account to buy some item if clicking 3d object to connect shopify-shop-item.
But Cart doesn't remember what add to my cart when I close unity scene I made.
During playing unity scene it works,though.
I think SessionID or Cookie cause this.
So should I made shopify-app to get SessionID from shopify-server and to send it to Unityapp?
Could you give me some examples to deal with it?
