After adding the comment function by episode, why did the number of posts decrease in the support window?

Since the comment function by episode was updated, it seems that fewer people are leaving comments in the support window. Is this a natural phenomenon? I'm curious about why this change occurred. Could it be that the way users leave feedback has changed due to episode-specific comments? With the ability to leave comments directly by episode, it seems that users are using the support window less. In the past, the support window was the main communication channel, but now that users can leave direct feedback for each episode, it may have naturally decreased. What do others think about this change? Do you see this phenomenon as a positive change, or are you disappointed that the role of the support window has been reduced?
