Recently my course cards and banners have not been syncing appropriately. When I upload a banner and a course card (different photos), and look at it from a computer, all is fine. However, when I log in on a student ipad and use the Canvas app, the course card shows up as BOTH the course card, AND the course banner. My students do not actually ever see the banner I have provided. The sizes are correct, and so are the type of file I am uploading. This seems to be a glitch within the system. Any suggestions on how to fix this?
