Hello Community -
Apologies for the difficulties!
Please note that our active content tool only operates on active listings on eBay that are eligible for revision - it makes no changes to data in your saved listings and the release that Johnnie Q. referred to prevents new listings from getting up to eBay or being saved with active content in them. So, if you try to post a listing from your Saved listings that has active content in the description or is using a profile (including a seller details profile) that has active content in it, it will not post to eBay (or save in the case of a new listing) until that content has been removed.
Unfortunately, there is no way for us to tell without having a look at your listings where the active content is. So, if you are unable to determine where an issue lies with listings receiving such a message, please feel free to file a support case with some examples of where you are encountering the difficulty so our support team can assist you.
