After the passage of the mission, there is no experience and loot. You need to re-log and re-pass the mission 2-3 times. In the end of the mission in the chat is written: "player" left the game.
I am having the same issue. No XP gain or loot from missions.
I also encountered such a problem. I'm waiting for the mission, I press "accept", getting on the ship does not get loot and XP. The Internet is fine. Game reinstalled, did not help
