I see a lot of posts in regards to the built in persistent cart not working as expected, IE - doesn't work for guests. What I'm trying to do is actually implement it.
It seems fairly easy. Store the quote ID in a cookie and load it and assign it to the session the next time the customer comes back. However I'm not having success. I've worked my way through the code when a guest first adds an item to their cart. My thought was that code would show me how to initialize a cart. Instead of initializing I'd load an existing cart. I've assigned the loaded quote to the checkout session and cart singleton but it still shows me no items when I visit the cart page.
Can someone point me in the right direction? I'll keep digging in the meantime.
