Currently, instructors and students have been having issues uploading and downloading files submittedCommunication through instructions is not enough as some students still gloss over them or may not know how to check file sizes.
Thanks for sharing this idea. The ability to upload a file to an online assignment is part of the Assignments tool; files uploaded to a quiz impact the file upload question type in New Quizzes. As these are two separate features within Canvas, these would have to be considered in separate conversations.
If you'd like a new setting in Assignments that allows the instructor to specify a size limit for file uploads, please write that as its own idea; if you're using New Quizzes and have run into this issue for file upload questions in the new quiz tool, please submit that idea separately. How do I create a new idea conversation in the Canvas Community? provides guidance on writing singularly-focused conversation prompts.
