When you mention that the CSV import showed everything had updated correctly, did it give you any sort of status message indicating this success?
We do have documentation regarding how to use CSV import for advanced parameters in PrestaShop
Did you ensure the CSV
file you were trying to upload was indeed one for categories, and that you also selected Categories
from the What kind of Entity would you like to import?
It sounds like possibly either the wrong Entity
has been selected and that's why you're not seeing the update, or that the Field separator
is in use. Did you simply export your products from your PrestaShop admin, and then edit those? Or are you adding to them as well?
I believe PrestaShop has a limit of exporting 300 products at a time, so it might also have the same limit on importing them. I might suggest trying just a handful of products to import to see it works that way.
Please let us know if you're still having any issues at all.
