It started to happen recently after I noticed there are changes on the UI from Amazon's end. I usually have no problem adding new products from this brand for the past years as long as I entered correct information (UPC, product details and such.). Few weeks ago, I tried to add something new as it is not on Amazon, just as usual. After I filled all the required information, I clicked Save and Finish, it loaded for around 2 seconds, then nothing happened and the button is back as if I had not clicked it. I kept trying and nothing happened.

Then I contacted Seller Support, they talked about cache and cookies... and recommended me to use Firefox. So I downloaded Firefox freshly, and started it over but same issue happened.

I still tried it once a few days now and that button is not working at all. The only change is that it is now Submit button instead of Save and finish, but it does not work... at least for me. Anyone else here has the same problem or if you guys have any suggestions?
