Bb Grader file download error
Due to changes implemented by Box Inc., you'll see different behavior in Bb Grader for inline grading.
After your institution transitions to the New Box View API, inline grading in the Bb Grader app will show an error when you access documents for the first time. Subsequent views properly render the document. All other features in the Bb Grader app will continue to function.
You can work around this issue by closing and relaunching the Bb Grader app: double tap the home button, swipe Bb Grader to force close it, re-open Bb Grader, and open the submission.
