But if I un-check it, now I don't get the icon to preview, but an arrow that produces a drop-down with preview download and Other formats options. But with the new assignment I just created, the two checkbox options are still there, and I can check the auto-preview checkbox, and that works. In the previous pages (assignments), they now show as links with a preview icon that they can choose if they want to preview in-browser/in-Canvas.
I was using the 'auto preview' feature and decided to turn that off. I'm an instructor, and I've been building a course with PDFs embedded.
