Various Issues - Chromebooks

Browser Impacted: Chrome

Students do not have permission to view files shared through Google Drive

Issue: Students are given a "You Need Permission" error when trying to access Google Drive documents shared by their instructor.
Description: We have two separated Google domains, Rebelmail (@unlv.nevada.edu) and UNLVMail (@unlv.edu). By sharing with "Anyone at UNLV with the link," it will only share within UNLVMail and it will not be available to Rebelmail users.
Fix: Change sharing settings to "Anyone with the link."

LockDown Browser

Student unable to begin a quiz that requires LockDown Browser and a Webcam

Browser impacted: LockDown Browser
Issue: For a course that contains an exam that requires LockDown Browser and a Webcam, when students click to begin an exam they encounter the following error: Unable to Continue - Exam title indicates a webcam must be used, but the course is unknown to our system. Solution(s): Ask your instructor to go to the "LockDown Browser Dashboard" for this course and check the setting for this exam.
Fix: The error is often caused if the course is a copy of another course, and the instructor has not yet opened the LockDown Browser Dashboard in the new course. It can also be caused if the quiz you are trying to take has been migrated into your course from an older one. Once the instructor clicks on the LockDown Browser link from their course menu, the problem will typically be resolved.
