Why does the cart reset on the Dawn theme?

Hello,

I have just migrate to dawn theme and the cart is resetting itself and it allows my customer to buy only the last product added to the cart.

Is this a general shopify issue or is specifically to dawn theme?

Yesterday, everything worked just fine, I was just announced by a customer regarding this issue.

Can someone help me fixing it?

This is my store. Maybe you can do some tests also.

@IrinaCelestia i’ve checked store by adding the product and i see that i can add more than one product not only the last one product as u r saying.

I had a preview for a few minutes with the Debut Team and this is working. For Dawn theme I don`t see the “add to cart button” and I see only the “shop now” button and is still not working.
