How do I go about disabling the default wishlist for users? I only want each logged in user to see and be able to add to their own wishlists, not a world-wide public default wishlist. When I remove the default wishlist setting in General, the add to wishlist popup button shows a null wishlist unless I have a default list set.
You must add a default wishlist ID! This is mandatory because when a user directly presses the heart icon, it's automatically added to the default wishlist.
And the items added to that list will be different and not the same for each user. Also, it's private!
(you can experiment this with different users)
If it's still not working as expected, I suggest you share a temp login to our support email: email@example.com
