Can't Copy and Edit a listing

[VintageJewelryNJunk]

Is this a new and annoying feature that Etsy has decided to inflict on us? That I can no longer copy and edit an existing listing? Because that's what's happening? I've seen older posts about this, but not a single solution. So does that mean this a new thing and that copy an existing post to make my life easier is no longer an option? FYI I don' use an app to write my listings, if that means anything.

You should be able to make a copy of a listing if you do it from the Listing Manager page.

What is happening when you try to copy an existing listing? Is there an error message?

I used to be able to do that, but now it won't let me change the price or the cost of the item. Just the picture. When I try to change the price it says the price must be a positive number, but it won't let me put a price in.

I can still click "duplicate" on the original listing.  This opens the original listing as a duplicate to edit for a new listing.

But it's not working anymore. That's what I used to do. I tried from different pages, but it still won't let me change the price or cost. And a list of prices comes up like a drop down and it will only let me use those listed prices. None of which work for me and the item I  wish to sell.
