I just started playing Destiny 2 on PC via Steam, and for some reason they decided that my Display name would be my real name. When I went on Bungie's website, however, it showed a different one. Obviously I don't want my IGN to be my real name, but I can't seem to be able to change it, what do I do?
Wait.
Bungie covered all of this in their TWaB newsletters just before cross play was introduced.
Bungie are planning a method of changing your tags but have not confirmed a date.
Keep a eye on the weekly TWaB newsletters for any information as that is where we will hear anything about this first.
