I have tried to finish the new exotic mission 3 times and every time I get to a point where there is no little triangle to shoot to bring down the boss's shields. I do everything I'm supposed to do but there is no way to continue the fight. WTF?!

Wipe and try again. It’s a known bug. I’ve had it happen several times in a row. Still hasn’t been fixed in the 2nd week of the mission. Typical Bungie
