I have a PSN account and I recently bought my daughter a PSN 1 year subscription because she wasn't able to access the PSN network. I thought I put her as a sub account and linked her to my account, but I guess I was mistaken.
She now has used the 1 year subscription, but I would still like to link her to my account. After I choose the link account and enter her current email address, it has a pop up that says the account is currently used.
If I am able to link the accounts, which should have been linked already, I would like to know if the PSN network accounts can be merged together and the remainder of her account just added to my current end time.
