Coming from Bungie:
As a follow-up to reported incidents of emote glitching in the Crucible, we are investigating a fix that we plan to deploy during the first week of November. In the meantime, the next two instances of Trials of the Nine will be postponed. Please stay tuned for updates. We will provide more information as it becomes available. At this time the next instance of Trials of the Nine is forecasted to resume on November 3, 2017.
They seem to be having a lot of trouble with exploits being discovered in Destiny 2. Hopefully they get it all sorted out soon.
