Trials of Chaos Elevators not Functioning correctly

higher level trials of chaos elevators to go to the next challenge will sometimes just not allow the players in the lobby to progress to the next trial. this has happened on nearly every single level 80+ inscribed ultimatum that ive attempted for loot.

I just had the same issue. I finished the room with the vaal soul cores, but can't progress further, because the elevator that is supposed to take me to the next trial doesn't activate, no matter what I do. The lever next to it is inactive.

same. bricked my trial. waste of time.
