I tried to give a MasteryConnect test through Canvas two weeks ago as normal (by creating a Canvas assignment with MasteryConnect as the submission type), but students were unable to access the test. It gave them the error that the test was not found. I ended up giving them a hardcopy of the test and I graded it by hand. When I went back and entered each student's responses question by question on MasteryConnect so I could collect mastery data, their tests were scored on MasteryConnect, but these scores only synced to the Canvas gradebook for 4 students out of around 60.  

Last week, I tried to give another MasteryConnect assessment via Canvas and it, again, gave students the error that the test was not found. So, I had students access the test directly through MasteryConnect. They were able to take the test and it was scored by MasteryConnect.  But these scores also only synced to Canvas for a handful of students. 

How do I force the syncing of these two test grades for ALL of my students. Please do not tell me that I have to manually enter grades into the Canvas gradebook after I already had to manually enter student responses for each test question on the first test for two classes.
