can't open documents in canvas

[MargretheH]

When I try to open uploaded documents, PowerPoints or other files in Canvas, it won't open. The page is just blank, so I have to download every document to my computer to be able to see it.

Are you trying to open them from within Files, or from within an assignment or page?

If you go to Files and click on the file itself, does it open up to show anything?

This is a problem for me too. The file opens, but they're all blank. It works opening files on my iPhone, but not on my Mac (if that's relevant). This is the case for all the files on my canvas.

Last week it worked just fine but this week I have to download the document on my laptop, email the document to myself and save it to my Galaxy tablet so that I can take notes during class. This all has to be done before class and if the teacher adds anything, I will not be able to access it until I get home from school
