We’ve discovered an issue with today’s scheduled update, but we’re hard at work to resolve it. We’ll stay in touch with more information as it becomes available, and share an ETA as soon as possible.
We now expect today’s update to become available at 1:30 pm PST. Some players on mobile devices may experience issues with sound or animations. We plan to roll out a hotfix for affected players in the coming days. Thanks everyone for the patience. (source)
