When I share google drive links through Canvas (i.e., of ppt slides where the accessibility is already set to "everyone with the link" within Google Drive), it still shows the "You need access" message on Canvas. I've had students send in requests for access, and it doesn't seem to always go through.

What do I need to do so that the Google Drive link they click from Modules can be viewable on Canvas? Also, I'm using Canvas Free for Teachers.
