I see a new UI for the catalog backend. It seems it was updated just now. I am in the middle of trying to upload a new catalog JSON. But it won't let me upload it. All I did was, download JSON file from old playfab project and upload it to the new one. The only one that worked was the default catalog. All others get stuck when I hit upload button.
It displays the name of the JSON when I select it from my computer. I get stuck in the submit button. It doesn't submit/upload the JSON file from the other playfab account.
