I honestly dislike the new editor as well, it's very hard to find things and it all doesn't seem logical. It escapes me why this is considered an improvement. I sure wish we could still opt for the classic editor.
That said, I'm having problems, too: there doesn't seem to be a possibility anymore to set the focal point on the featured photos (thumbnails) of a shop? (Brine)
I use photos of small objects, so it's often necessary to adjust the focus. I can still adjust the focus of product images, but not of thumbnails, which makes the shop page look messy ðŸ˜
