Amazon recently began requiring a new "Is Heat Sensitive" attribute for Grocery & Gourmet Food, Health & Personal Care as well as Beauty and other similar categories. More information on this can be found in this Amazon post.

We have already added this new attribute to Zentail, and you can fill it out either under Edit SKU > General Info, or in a Quickedit view like this one in addition to being Importable.

If you see a listing error related to this new attribute and you've already filled it out, reach out to us as [email protected] and we can make sure its been included in your relevant Smart Types.
