It is not possible to change linked accounts while cross-save is active. This means that you will need to deactivate cross-save, putting your accounts into a 90 day cooldown period, before reactivation is possible. You would still have access to your save data during the cooldown, but only on the respective platform(s) for that data. Once the 90 day timer is done, you would then be able to reactivate cross-save, with your desired platform accounts. [quote]Changing Linked Accounts Players who want to change their Cross Save setup and link to another platform account because they chose the wrong account will have to disable Cross Save and wait 90 days before they can enable Cross Save again.[/quote] https://www.bungie.net/en/Help/Troubleshoot?oid=48099
