Hey, [quote]I recently noticed on the bungie website that DLC ownership for Xbox and the Microsoft Store PC version of the game seem to be tied together under the Microsoft Account (as shown in the linked image). Does this mean that if I purchase DLC for the Microsoft Store PC version of the game that it is accessible on Xbox as well and vice-versa?[/quote] Unfortunately they do not transfer the DLC licenses between platforms regardless of it being linked to the same Microsoft account as Destiny 2 is not "Play Anywhere" title. It is also confirmed in [url=https://help.bungie.net/hc/en-us/articles/4403617844628-Destiny-2-Microsoft-Store-and-Xbox-App-for-PC-Guide#:~:text=Destiny%202%20add%2Dons%20cannot,Microsoft%20Store%20and%20Xbox%20consoles.&text=Silver%20will%20be%20shared%20across,the%20Xbox%20app%20for%20PC.]this article[/url] regarding Destiny 2 on the Microsoft store. [quote]Destiny 2 add-ons cannot be shared or transferred between platforms, including between Destiny 2 on the Microsoft Store and Xbox consoles.[/quote] As for your second question regarding game sharing, that is also not possible. While you can share the base game any of the DLC's may not come across. [quote]Players accessing Destiny content through the game sharing feature may not be able to access all DLC, add-ons, promotional items, or pre-order items for which the primary account owns the licenses.[/quote] Quote from [url=https://help.bungie.net/hc/en-us/articles/360048719412-Playing-Destiny-Content-on-Multiple-Consoles-or-with-Multiple-Accounts]this article[/url].
