Post Disappeared from Market Pinball Wizard Chat Room

At 7:01 am today, Avi Gilbert posted a message to the Market Pinball Wizard chat room.  Some people in the chat room say they saw it.  For me and some others, this post is not there.  Searching for posts from Avi do not find this post.  No post from anyone is in the chat listing, at 7:01 am.  Avi insists he posted it.  Someone else said he saw it on their phone, and then it was gone.
