The team expects the Reply tool to be deployed on Tuesday (probably later Tuesday, in your timezone).
Editors here have already used it hundreds of times, so I don't expect many new problems. However, the deployment will not be perfect. If someone has turned on the Beta Feature, didn't like it, and then turned it off, then they will have to turn it off again. Would you please tell everyone that the team apologizes for this? It is due to a bug in Preferences, and not normal.
