Hi there, Thanks for reaching out. As Shark_Shank kindly pointed out, enabling Cross Save requires that you first link all desired platform accounts to your Bungie profile. Currently, your profile only has an Xbox account attached, hence the inability to enable Cross Save. That said, please be certain you're linking your desired platform accounts, as doing so is a permanent action, with the sole exception of Twitch accounts. For more information about Cross Save and its intricacies, please consult our [url=https://help.bungie.net/hc/en-us/articles/360049498031-Destiny-2-Cross-Save-Guide]Cross Save Guide[/url].
