Hello @AmandaBoudreaux
Thanks for posting this in the Global Canvas Community.
I am sorry that you are having trouble with your grades from Cengage to Canvas. This question might be better directed towards Cengage's support team. I know that Cengage is supposed to feedback any scores and grades to Canvas once work is completed in their system. If it is not feeding back, your teacher might be able to have Cengage force a grade sync over to Canvas. Unfortunately contacting Canvas support might not be the best option since their overall access to any of Cengage products are very limited, if at all.
Have you tried reaching out to Cengage yet about this? HERE is a link to their page.
