After trying a step – attempt to submit your work! Don’t try all of these at once!
1. Restart your iPad
2. Check the AppStore and make sure Canvas and Goodnotes are both up-to-date.
3. Delete the Canvas app and Reinstall
4. Do you have a lot of open tabs in Goodnotes? Try closing a few and try again.
Contact the helpdesk if you are still having issues!
