We have a Rise course that includes Storyline blocks as lessons. About a week ago clients started complaining that random Storyline blocks within the Rise course were not displaying properly, blocking users from continuing the training. The Storyline blocks appear as black shapes with no player controls or content visible. We've republished for Scorm 1.2 and reloaded into our LMS. We can't find any errors when testing in Rise. But that didn't solve the problem. For different clients, it's different Storyline blocks that are not functioning. Any idea what's going on?
