I need help adding/hopping on new listings ever since Amazon completed their update. Has anyone else had this issue recently? See below for the issue description. This is under incomplete listings

"You are receiving this error as you may be adding Offer-Listing(s) or editing an SKU not present in your catalog or one that’s been deleted. If this was a deleted SKU, wait 24 hours before resubmitting it. If you tried to add this SKU to the Amazon catalog before, check your data and correct any errors before resubmitting. If product is being added to a marketplace from another one, it may require few hours for localization before it is valid, please check your seller account for progress or any issues."
