Can't Write on PDF Submissions

[ALEXANDERBROWN2]

The last week, many of my student's PDF submissions are no longer giving me the option to write on them to give feedback using my Apple Pencil.  Today, assignments I had this option for yesterday are no longer able to do this with.  All the submissions are PDFs and I am grading them through the Canvas Teacher App on my iPad.

Hi! I tried this in a test course, and I experience the same thing. Have you opened a case with Support? How do I contact Canvas Support? 

I noticed that it happens inconsistently -- meaning, some PDF submissions had the annotation ability and others did not. Do you experience that too?
