Multiplayer Doesn't Activate for Un-Played Matchmaking Selections

Players trying to activate matchmaking may run into an endless loading screen if none of the players in said party have previously entered the gameplay selection they're using and activated the respective Fast Travel stations. 

This can apply to Bounty Pack Playlists, Takedowns, and Raids. To bypass this, please have all players in the party start the mission in single player and activate the respective Fast Travel stations to allow multiplayer gameplay to begin.
