Currently ist is only possible to assign products to categories with the uuid of the category, ist should be part of the category export.
Since the category name is a non-unique field, it is not usable for an assignment
Thank you for your reply.
So I also tried that. I have about 10 categories, it was not a problem to find all the UUID for each category in the database and put them in the import CSV file instead of the text value. But it also did not work. Maybe I should try again, could this work? Or it is also not enough?
