How to change SAME DAY SHIPPING to ONE DAY HANDLING bulk in all my 1800 listings?

[maxmawi]

I have 3 hours trying to find the way to change the commit time to ship from SAME DAY to ONE DAY HANDLING. I don't know why eBay hides easy tasks and make them so difficult to find. Please somebody help me step by step. I am an old person and not familiar with technologies. Thanks a lot! I am standing by here

Hi @maxmawi 

You can change your handling time in the listing form. If the option is not displayed, you can fix that in the listing form here:

First click See shipping options (highlighted) to display the dropdown, and then flip the switch for Handling cost to blue (which means "on").

Why eBay hides this only eBay knows...
