Cannot Zoom Out on iScanner PDF Submission

I'm having issues grading PDFs submitted by students from the iScanner App. From what I can tell, it's a regular JPEG to PDF converted file with no special traits in the metadata (though I'm not the best metadata diagnoser). Could there be an issue with how Canvas interprets these files that makes the PDF viewer think it can't zoom out any more? I haven't had trouble with any of the other PDF submissions by students using other apps, for some reason it's just iScanner.


Any help from someone who better knows how Canvas displays PDF's in the speed grader would be greatly appreciated! Attached is an example document showcasing the issue.


Hopefully this issue illuminates a more general issue/bug with the speedgrader reader...
