Interesting. This is all surprising to me, but I honestly don’t know what to conclude from the surprise:
Even when logging into OpenReview, I do not see a single comment from the area chair.
So if what you are saying is true, then the area chair communicated their unhappiness to you, but not to us reviewers. My usual expectation is that the area chair initiates the reviewer-AC discussion, which, as far as I can tell, simply did not happen at all. (This can sometimes happen if the AC thinks no discussion is necessary, but according to what you say the AC would have liked MORE, not less discussion)
You write about a “final decision”, but, crucially, when I look at OpenReview, I do not see any AC decision. Instead, I see that you withdrew the paper on 23rd of January, one day after the decision should have happened according to the dates and deadlines.
I’m not sure what to make of this.
Thanks! Apparently this is not visible to me as a reviewer.
Then my current guess is that the area chair forgot to initiate the AC-reviewer discussion, or that they set the visibility wrong.
