So, I have a sub-account (I'm 18 in three months, not 12), and I don't seem to be able to sign in to PSN.com OR bungie.net with said account. Everytime it comes up with an error. I have all my progress on the sub-account, therefore I cannot access my grimoire cards, rewards, or even properly join clans in-game. I have access to the master account, so is there a feature that could enable my ability to use the sub account? I tried just linking the master account, but it did nothing in-game with the sub account.
