When you add a simple product that is configured with add-ons (that affect the price or not) to your cart to then be shared. The products in the cart that the customer sees do not match the said configuration. Sales king seems to be removing the add-ons on these products. Keep in mind this works as expected with variable products ( variation + add-ons work) just for some reason if it's a simple product it won't account for the add-ons you've configured. I don't quite understand why this is so. Attached are screenshots of this discrepancy.
add-ons not visible is what the recipient of the shared link sees.
add-ons visible is what the agent sees.
Also in the dashboard these add-ons arent visible either (see dashboard-preview)
