IMPORTANT - Unity removed link to rss feed from info page.
You can still get this to work by going into Verify Invoice section in publisher's account and copy API Key, then replace default key in Unity publisher's bay app link.
https://publisher.assetstore.unity3d.com/feed/irrelevant-section/HhyauiaVobiU35pTCWBLLTMIMDE/activity.rss

So in above example replace HhyauiaVobiU35pTCWBLLTMIMDE with your API key.

As a unity asset publisher you can get instant information regarding customers feedback/review for an asset. I personally could not find anything usable that will inform me that someone wrote positive/negative feedback. It helps me now to instantly reply to users having issues with an asset and resolve it. Thanks to that system I managed to improve ratings, customer satisfaction which finally lead to more sales.
