Blackboard will be migrating its mobile services to a new server this weekend. As a result there will be no access to Blackboard content via mobile apps during this time.
When: Saturday, July 23, 2016, 12:01am EDT to Sunday, July 24, 2:00am, EDT
Workaround: Use a desktop computer or the web browser on your phone (Safari, Chrome, Internet, etc) to access Blackboard.
