problems with guest mode

Summary:

I'm having problems using 'guest' mode in Commerce, when the user adds a product to the cart and goes to the 'shipping' page and returns to Home, the cart is lost, I saw that an unauthorized error is generated in the request '/ccstore/v1/orders/current?exclude=shippingMethod' which is executed on Home, from what I saw that the API '/ccadmin/v1/merchant/profilePolicies' already shows that guest mode is activated:

{

"allowedSymbols": "~!@#$%^&*()_-+={}[]|:;<>,./?",

"guestCheckoutEnabled": true,

(…)

}

So I would like to understand if something is missing so that the cart does not get lost, even when it is a guest
