Hi there. Instead of deactivating Cross Save, which would result in having to wait 90 days before you could enable it again, you could ask Bungie to switch your Active Account to Steam. To do so, head over to this article and fill out the contact form at the bottom. https://www.bungie.net/en/Help/Troubleshoot?oid=48099 Please note that Bungie goes through these reports in order that they receive them, and only during normal business hours Pacific Time.
