I see that sellers have had this problem as long ago as 2017 and the tech idiots still haven't fixed it. In seller preferences I switch off "Keep listing when you're out of stock" because nearly all my listings are unique. But Ebay just switches it back on again and my defunct listings remain. Why does this happen? Why would they have an option that auto defaults like this? I have told customer service many times about this but it looks like they are utterly incapable. I have to manually end my sold listings one by one. About time they fixed this! Or hired someone who actually knows what they are doing.
