Is there any way I can find out what Steam ID is currently linked to my bungie.net account? When I try to authenticate my current steam account through bungie it tells me that I'm logging in with the wrong account information and to unlink the steam account being used with bungie. Problem is I can't unlink the account because there is no way for me to authenticate it in the cross save settings. It just tells me that the login information is wrong. I don't recall ever using a different Steam account to link to Bungie so I'm not sure how this happened. Currently I can only play the game through Playstation, If I try steam it does not load my characters.
Have you checked: https://www.bungie.net/7/en/User/Account/AccountLinking to see if it displays the steam id? thats the best you're going to get from Bungie.net
