I have this problem since the launch of Destiny 2. PvE activities who use matchmake simply don't work with me. I find people in matchmake to play Crucible or Gambit, but in the Menagerie or the new Vex Offensive it keeps "looking for other players" and "evaluating guardians" for a time, then the activite starts with me alone. Xbox says my NAT is ok and I really don't know what to do anymore, once it gets impossible to do such activities without being in a fireteam. Hope someone can help me with this issue.
