What's up, ballers?
We're aware of an issue affecting early tip-off players (meaning you've been given advanced access to the game because you pre-ordered it) on Xbox One.
Some players are unable to share Achievements, screenshots, game clips, or rich presence and activity feed won't display NBA 2K16 content.
In the words of Douglas Adams: DON'T PANIC!
If you are encountering this issue, the content you want to share will be shareable when the game launches on September 29th, 2015 (local midnight time).
