If a student submits an assignment with an attachment that has an apostrophe in the name, going in to view the attempt the inline grading viewer will be stuck in “Loading… Please wait while we render this file”. It will stay on this page and not render the file, even though it is a supported file type. This may cause you from being unable to submit the score in the inline viewer too.
This is a known issue with Blackboard and will be addressed in future releases. We recommend you make sure you students know to submit files without apostrophes.
