Did they change this to once per account per day? I just did this JP with all of my characters yesterday (at 1 am) and now it only let me open the chest with my first run. It’s 2 am now so I know it’s reset (plus it worked for my other character too). The chest is closed and it brings up an option to unlock but clicking it doesn’t do anything. Is this a bug or did they change this?
Edit: just did it again with my 3rd character to be sure it wasn’t an isolated case and it still won’t open
