I just finished and published my first course. Then I decide to make a few small changes to two of the videos that are part of the free preview. So I uploaded the new files. In my instructor dashboard, I can see the new files are there. But when I open an incognito window and look at the preview, the old videos are still there. I've tried this in both Chrome and Safari. I did email support, but haven't heard back from them. Any suggestions on what is going on and how to fix this???
