Shopware will calculate the cart only when accessing the cart (add product to cart, open the cart, …), not on site visit, because of performance reasons. So when the session ends, the cart isn’t stored in the session any more, but in the database. Accessing the cart adds the cart backt to the session.
Ok, but when a session is re-created, surely it can be regenerated then? It’s a one-off expense vs the customer wondering why their basket is empty. They could either leave, thinking they have lost everything they put in, or put in the same thing again and not realise (people do sometimes order like that).
Do you not think it is worth changing this?
And thanks again for helping me find the solution, I’m not having a go at you here, I just think it’s something that should be fixed.
