This seems to be an ongoing off and on issue with etsy. I am ready to publish a listing and it won't allow it stating "core details" needs to be done. It is done but nothing changes. Very frustrating. Anyone else??
I never create a listing from scratch. I use the duplicate feature on another listing and then update. Never had a problem.
Are you able to do what NanaLetha does & use the Copy feature to create new listings? It’s not a fix, but hopefully a workaround until a better answer comes.
