Today when testing my code I noticed that when trying to buy margin blocked stocks, we get an exception. Previously, we used to get this as rejected when placing orders. I did not intend on actually testing this and did it by chance. Although this change is welcome, we should have some way of knowing about such changes. Due to this lack of notifications, I'm having to test every single part of my code every week, which is not optimal because there is a good chance I may miss something and can cause unexpected losses.
Even after repeated attempts for this request, there has been no response. We are paying customers and deserve atleast minimal notification for any changes made
