I have embedded PowerPoint files to my canvas. They can be viewed by students if they log onto a computer but for most students who use iPads they only get a box that says Sharepoint online sign in.
I have tried chrome, safari, and the canvas app. This appears every time on the iPad
Try this: Solution without resorting to Google or OneDrive or O365 is to:
1. Insert the file.
2. Select the file link.
3. Select Link options.
4. Automatically open in-line preview.
