Custom Wishlist problem

Hi,

I have a problem with the custom wishlist. The problem is more for the sharing list to an external person.

I created a custom list and I added products into it, then under the list I click on the icon to copy the link of the wishlist so to not have the session user open I open another browser and I paste there the link, the page shows up but under the custom list, it doesn’t appear any products I added.

So after this I was curious if it was just for the custom list so I try to add products to the default wishlist and when I tried to share it by link, this is showed up all the products inside. I could stay with just the default list, but I need to have multiple wishlists for a user, so I would like to solve the problem, if someone had encountered the same problem, I’m grateful for the help, thank you.
