I have not been able to preview my listings / while editing or creating new - all day today. I saw on fb post that others are having the same issue.
On the new template, you cannot yet. Etsy said it is coming.
It's happening on the old form as well.....
I've just posted about this very thing, when I searched the forum your post didn't show up.
Agree! @TwoDogFarm for a very long time now!!
I know what you mean, I have been waiting for hours to preview/edit my new listings before I put them into my shop. Somethings not right. It just spins and spins, so I just have to save it in draft again. Sure wished this would get fixed!
