I am running the opensource version of Canvas LMS and I notice that while I can see assignments in speedgrader I cannot annotate. I do not see the features of Crocodoc. Is there something I need to check specifically? I tried searching to see if anyone had come across this the closest thing was one discussion that talked about the Google Documents Viewer. I have turned that off and the Google LTI and that did not change my ability to annotate on assignments. Even when the student submits their assignment as a PDF it does not give the annotate function on the assignment.
I am running the lastest Stable Production version of Canvas LMS on Ubuntu 14.04.
