I did this last month and suddenly, the expiring items appeared again. I checked the supplemental feed schedule and it still says Daily. Do I repeat the same procedure above and create a new supplemental feed?

Will this work for already expired items that are still showing in my local product section? So when I download all products they are still there but just not showing in my content API

I tried doing that, but it still did not update all. It claims some are not matched but not too sure what to do about those

Hi Emmanuel,

Thank you for the great information, I followed method 3 but it didn’t work. When you say column ID, can you share a screenshot. When you turn the document to CSV there is no column ID.
