Destiny 2 is up and running, but not all of its features have gone live. In-game Clan functionality has yet to get off the ground, something Bungie made clear to the game's userbase on Twitter prior to launch.
In-game Destiny 2 Clan Features will be unavailable for the first several days after launch. Stay tuned for announcements of availability.— Bungie Help (@BungieHelp) September 5, 2017
The alert was issued Tuesday morning (via IGN), noting that Clan features will be made available in the days ahead. Destiny 2's other online features are active, though the game is in the midst of a rocky launch. Bungie has collected the myriad of issues on its forums, including 503 errors on Bungie.net, CABBAGE error messages, and PS4 Pro crashes.
Clans can still be created through the Bungie website, but look for full in-game functionality to start up in the days ahead.
