When i transferred the account i logged in through steam on pearl abyss website and whenever i tried changing the password or linking it said "You must login as Pearl Abyss member to use this feature".....it still keeps saying that even after the transfer. So what's the problem here? Steam users can't change their passwords or link their accounts if they logged in through steam?

I also want to change my main mail address but there's nothing at alternative or a change mail button like on kakao :|

EDIT: Also the other options with package history/purchase history/game security center also say "You must login as Pearl Abyss member to use this feature".
