To submit a late Canvas assignment when the "Submit Assignment" button is locked, take a screenshot of your assignment page and upload it to ApexVision AI. ApexVision AI gives you precise, step-by-step instructions-including the fastest way to contact your instructor, what to say, and how to attach your work for late submission. Canvas doesn't let students submit after the due date unless the instructor unlocks it, but our team has helped 500+ students get their work accepted using this method.
Key Takeaways
- Canvas blocks late submissions unless your instructor unlocks them-student settings can't override this.
- Using ApexVision AI to screenshot your locked assignment gives you custom, instant advice on what to do next.
- Messaging your instructor directly with all assignment info and your completed file speeds up the process.
- If your instructor doesn't respond, ApexVision AI shows you alternative options for getting your work counted.

- Contact School Support or Canvas Admin: If your instructor is unresponsive, use your school's Canvas support or IT helpdesk. Send them the ApexVision AI message (with proof of your contact attempts) and ask for the assignment to be unlocked or escalated.
- Submit by Email (if approved): If your instructor replies and allows it, email your assignment as an attachment to their school address. CC yourself and use a clear subject line ("[Course Name]-Late Assignment Submission: [Assignment Title]").

Step 1: Screenshot Your Locked Assignment With ApexVision AI
On your assignment page in Canvas, take a screenshot showing the missing or greyed-out "Submit Assignment" button. Then, open ApexVision AI and upload the screenshot or use the Chrome extension/mobile app.
Why this works: ApexVision AI instantly scans the page, identifies the lockout, and gives you a tailored script to message your instructor. No guessing what details to include.
Pro Tip: Make sure your screenshot includes the assignment title, due date, and your Canvas username. This helps ApexVision AI generate the most accurate step-by-step instructions.
Step 2: Contact Your Instructor via Canvas Inbox (with ApexVision AI Guidance)
Open Canvas, click "Inbox" on the left sidebar, then "Compose a new message." Select your course and instructor. Use the message template generated by ApexVision AI, which includes assignment details, a polite request, and your completed file as an attachment.
Why this works: Only your instructor (or the course admin) can change submission settings or accept late work. ApexVision AI ensures you cover exactly what they need to unlock your assignment or allow an email submission.
Pro Tip: Attach your finished assignment file directly to the message-even if it's late. This shows initiative and saves time if the instructor decides to accept the work right away.
Step 3: Monitor for Instructor Feedback or Alternate Submission Links
Go back to your Canvas assignment page. Check under the "Submission & Rubric" or "Comments" sections for any response. Turn on Canvas notifications so you don’t miss instructor replies.
Why this works: Instructors often respond by leaving a private comment with directions or a unique link to submit your work.
Pro Tip: If you use AI study tools like ApexVision AI, you’ll get reminders to check Canvas and tips for following up if the instructor doesn’t answer.
If That Doesn't Work
Still need help? ApexVision AI offers step-by-step troubleshooting for Canvas lockouts and even templates to escalate your issue to department heads or advisors.
Troubleshooting
Problem: "Submit Assignment" button missing or greyed out.
Solution: Clear your browser cache, try incognito/private mode, or switch devices. If it's still locked, only the instructor or admin can unlock it (ApexVision AI gives you the exact script to request this).
Problem: Instructor doesn't respond to messages.
Solution: Follow up after 24 hours using the message template from ApexVision AI. If no answer, escalate to the department head or Canvas support with proof of your attempts.
Problem: File upload error or unsupported file type.
Solution: Check the accepted formats (usually PDF, DOCX) and file size limit listed on the assignment page. ApexVision AI can detect file type issues and recommend the right format.
Problem: Canvas Inbox message not delivered.
Solution: Check your "Sent" folder. If the message isn't there, resend it and email your instructor directly. ApexVision AI walks you through this backup plan.
