Its a PITA, it means creating a new add from scratch again…
Can’t you just copy paste the contents? I get you’ll need to reupload the images mind. Get that’s a bit of a pita from a seller perspective but they don’t expire completely do they? (can’t say I’ve looked but assume I can still see months old ads on subsequent pages)
From a buyer perspective though I can’t say I think it’s a terrible thing, PB and ebay particularly seem to be almost entirely the same 30 ads permanently recycling to the top so you end up missing the actual new ones.
