Hello @mmsntos124
If it shows as submitted on your end, but the teacher can't see it It is likely their internet browser and we recommend clearing the cache and cookies or trying another browser.

At the top, choose a time range. To delete everything, select All time. I suggest at least 4 weeks

If that doesn't work, it may have had an issue uploading. There have been instances where students submit files and the file shows for the teacher on the right of speedgrader for downloading (they should be able to do this) but not displaying in the speedgrader view. You can either resubmit, or ask the teacher to speak with Canvas Support to re-render the submission. This is all maybe and depends on the specifics of your assignment and submission.
Because of the complexity of the issue, and the concerns for privacy, it would be best if you contacted Canvas Support directly to pinpoint the source of the issue and provide a resolution:
