Hi there, Thanks for reaching out. Checking your profile in our system, we can confirm you haven't yet activated Cross Save. To that point, can you confirm you're attempting to do so via the setup button on [url=https://www.bungie.net/7/en/CrossSave]this page[/url]? If you are, please know you'll need to authenticate all linked platform accounts, which would indeed be Xbox and Steam in your case. If you believe you're authenticating both platforms correctly and are still getting authentication errors, the most likely explanation is that one of the platform profiles you're logging in with isn't the same one that's linked to your Bungie profile. To double check this, we recommend opening Bungie.net in an incognito window and then logging in and out separately with Steam and Xbox, one at a time. If you get an authentication error for one platform, this indicates that the credentials you're using for that platform's profile are incorrect. This will then help you determine which platform profile you actually have linked, and using those correct credentials in tandem with those of your other platform profile should allow you to set up Cross Save.
