There is neither an "X" nor a "No, thanks," prompt, so your admonishment to "ignore the prompt by clicking the X or No, thanks button to close it," is complete nonsense.  This refers the despicable new feature that I cannot turn off called DISCOVERY HUB.  A bridge too far.  Please provide the option that you tout in your response to our desperate pleas for relief from the onslaught of advertising of your products.  This is in the Desktop application.
