I gave a midterm exam via canvas and graded all exams. The grades never downloaded into the grade tab in Canvas and now they have disappeared
I'm sorry to hear that this isn't working as you'd expect. This is very much a guess, but it sounds like you may not have hit "Submit" in SpeedGrader. If you visit SpeedGrader for the quiz again, your assessment scores should still display in the Grade section. You'll need to find and click the blue "Submit" button. That will push your entered grades to the gradebook.
Hopefully that helps. Please let us know if you have any follow-up questions for us.
