I have a teacher who created a Google Doc with images and attached it to a Google Cloud Assignment. In Canvas some students are reporting that they only see a grey box with an exclamation point icon inside it instead of the image. When the teacher shares the document directly with them from her Google Drive, the images load. She did say she dragged the images from her desktop instead of inserting, so my inclination is there is some permissioning issue, but not every student is running into this issue, and I was able to preview the document in Canvas without any problems. Any thoughts?
