<p>I moved your comments in one question into a chat yesterday.  The system automatically leaves a comment explaining that and in that comment is a link to the chat.  You can read that comment at <a href="https://stats.stackexchange.com/questions/420032/proof-verification-joint-variance-of-the-product-of-a-random-matrix-with-a-rand#comment784843_420032">Proof Verification: Joint variance of the product of a random matrix with a random vector</a>.</p>

<p>This is routine when a large number of comments appear or when there seems to be an escalating back-and-forth conversation emerging.</p>
