Anytime I try and sign in with apple ID in order to pay using the money I have on my account it tells me the page doesn't exist. For the record I am trying to individually buy the Hexblade warlock using the cash I have on my apple account but on PC. I'm doing it on pc because I was unable to find out how to buy individual classes through the mobile app. Anybody have any ideas? Thanks in advance.

Edit: Turns out this issue just seems to be with signing in with apple in general on pc
