Apparently there is no setting for this. I also tried an older version of prestashop and the same problem. For me, this is a big drawback.
What turns out is that in prestashop, you must first log in to your account, and only then add more products to the cart to be added to the products of your previous visits. Because if you have not logged in to your account beforehand and added products to the cart, then once you log in to your account the products from previous visits will be missing. This is not serious.....
I did not expect that such a widespread platform lacks such a feature. Too bad for lost time and paid modules that added to my future site. I have been dealing with settings, etc. for months. The last step was to migrate the database from the old site. But it is good that I saw this problem before the final migration, obviously I will have to move to another platform.
If there is a module that solves this, please reply. I did not find one.
