I have been unable to join any of my friends to make a fireteam to enter The Prisoner of Elders. I have been trying to join for over 90 minutes after downloading the new update. The message I receive when trying to join my friends to make a Fire team is "Please try again later". I have rebooted my modem, and using a wired internet and have an excellent download speed from my IPS. Please advise where I am going wrong
