Redirection error in Hub

I recently went through one of your courses in the Academy section and made a few comments over there on those threads. The comment activity is showing on my Hub, but the link back to the comment/thread is broken is misdirecting. In the attached image, the highlighted link is targeted at, but when you click it, the redirect brings you to, so it’s just redirecting back to the Hub. Can you please take a look? Thanks.

Update: it also seems I’m not getting any notifications for comment threads over there to which I’m subscribed.

Update: In order to re-access content in the course I did, I have to click through all the way from the beginning, as though I’m taking the course again. This is a real usability issue. If I use the direct links on the course’s homepage, they all lead back to the course’s homepage.
