One of the recent course updates has broken the direct link to this course's Support Forum (SSAv2). Not very convenient to have a dead/outdated link and this could hurt participation. My guess is that since the last migration the forum identifiers got renumbered. The reference to https://pdn.pega.com/forum/14801 should become something like https://pdn.pega.com/forums/pega-academy/senior-system-architect-71 This problem could be valid for any other courses as well.
