I am a new user and trying to setup my products. When I go to edit a product and make changes to the attributes the page is super slow and keeps freezing. Then when I am finally able to finish the changes I want made, like updating the listing price and designating the product as imported, I click save at the bottom and nothing happens. The spinning icon pops up for a second as if it is saving, but then nothing changes, and the page looks exactly the same. I even tried reopening the product in a separate window to see if the change is saved, but they did not. I've been troubleshooting with seller central support for weeks and they can't seem to give me an answer. I tried all of the updates they asked, including deleting the cookies and trying different browsers like Firefox. Nothing works. Please help.
