I'm not sure if I'm doing something wrong here, but when trying to create a release I go to e.g. https://balrog.services.mozilla.com/releases/Widevine-4.10.2710.0/v2, then paste or upload the blob, but the form won't let me enter the product name, which means form submission fails. Going into devtools to replay the request having added the product to the request body does work.
