Hey there @Seller_vLFbFWvWeyhvI- thanks for looking to forums for assistance with this! To confirm, do you have any inactive listings currently that you are looking to activate? If so, here's some instructions on how to proceed! I'll also link to these instructions on how to add products in case that is the central issue here!

I hope this helps but please do let me know what other questions you might have.

Thanks!

Danny
