Destiny 2 Tracker Network
We are actively investigating matchmaking issues on all Destiny 2 platforms. Until resolved, players may be unable to match with other players in the Crucible or Strikes. Public and Social spaces may appear empty for some players. Please stay tuned to @BungieHelp for updates.

This is account wide - Not by Character. Unfortunately that is the only way to do it since it's based on Grimoire Cards.
